Solder antenna to 4 g modem Yota. We make an external antenna to enhance the Yota signal with your own hands. What you need to connect antenna

Good day. People living in a private house often face the problem of the absence of high-quality Internet. ADSL is now a little used, and the speed leaves much to be desired. It is especially problematic if the house is new and the phone is not, then the wire will have to pull the sake of not very fast Internet. And if there is a phone, it is not a fact that the line laid for a long time is suitable for the Internet. Fiber fiber is expensive. Some add up with neighbors and then costs can be acceptable. However, not everyone needs a good Internet. The mobile Internet remains. The 4G technology maximizes 150 Mbps, but for such a speed you need a high-quality signal reception. Not always a built-in antenna (more precisely two) modem is enough for this. So, today we will make antenna Harchenko for 4G modem Yota. At the moment there are modems of Yota 4G LTE WLTUBQ-108.

We have to:
- Yota 4G LTE WLTUBQ-108
- copper wire with a cross section 2.5 mm
- Iron leaf
- coaxial wire resistance 75 ohm, thin
- Pigtail Double with MS156 on SMA Female
- SMA MALE connector
- Drill
- 3 mm drill
- plastic tube or any dielectric
- soldering iron
- solder, rosin
- Termoklay
- CHOMICS
- USB extension

Step 1 Modem Preparation.
Before you start the manufacture of antenna, you should connect the modem to the computer. Going to the modem settings at 10.0.0.1, write the SINR / RSRP values. It is necessary to make it necessary to compare the change in the level of the signal after connecting the antenna. The modem disassemble enough. It is necessary for something sharp, for example, a seboard or a knife, pry and remove the top cover. It is necessary to do this very carefully, since the built-in antenna is under the lid. The main thing is not to damage it. Remove the lid:

And on the back, it looks like this:

Our modem supports MIMO technology. MIMO (Multiple Input Multiple Output, multiple inputs, multiple outputs) - spatial signal coding technology, thanks to which can be increased channel bandwidth. When using this technology, two or more antennas are used to transfer data and as much antenna for reception. In our case, we have two antennas. For each antenna its nest:

One socket is in the upper part of the modem, the second side of the right. It is not good to leave the modem, so applying the housing to the modem, measure the locations of the holes under the socket, and drill a 3 mm diameter drill:

It is accurate enough to extinge. Drilling holes that wear the body on the modem and see whether the holes with the sockets match. If necessary, we increase the holes with a knife in the desired direction. Making sure that the holes coincide with the sockets, wear the case and close the top cover.

The antenna will be connected to specially prepared nests. For this we need a adapter. On the one hand, which will be two MS156 connections (connect one antenna to two sockets), on the other hand, the SMA Female high-frequency connector. It can be ordered on Aliexpress or buy in the store radio components:

We connect the pigtail to the modem:

On this lay, on time, modem to the side.

Step 2 Calculation of antenna.
Antennas variants are quite a lot. In my opinion, the most efficient and simple in the manufacture - Antenna Kharchenko. She is named by the name of the engineer who developed and described the design of this antenna - Kharchenko K.P. Antenna vibrator will be made from a copper wire with a cross section of 2.5 mm. You can use a 2 mm cross section. The wire is easy to buy in the electrics. Before making antenna, the isolation of the wire is to remove. The vibrator consists of two squares connected in one of their vertices and with disconnected parties. The antenna wire is solder at the points of connection of the squares. Antenna's input resistance to 50 ohms. I chose a 75-ohm cable, although it also agrees well with a 50-ohm coaxial cable. The length of the sides of the squares is λ / 4, where λ is the wavelength. In our case it is 115 mm. We make the vibrator according to the following scheme:

Where:
Central Frequency F: 2600 MHz
Antenna wave resistance ρ: 50 ohm
Wavelength λ: 115 mm
Size L1 (outer side of the square): 28.9 mm
Size L2 (inner side of the square): 27.6 mm
Size L3 (total frame length): 81 mm
Size L4 (frame width): 40.5 mm
Size L5 (gap at the connection site): 1.7 mm
Distance Vibrator-Reflector D: 13.2 mm
Size B (Reflector Width): 115 mm
Size H (Length of the reflector): 115 mm
Vibrator wire diameter: 2.5 mm
Total wire length (with turns on turns): 237.9 mm

Step 3 Collect antenna.
We solder the wire to the vibrator. As a result, it should work like this:

The reflector can be made from almost any metal sheet. It is also possible to manufacture a mesh reflector. I chose and you recommend making it from the metal from the old system block of the computer. The thickness is sufficient, and the coating helps perfectly. Cut the square with a side of 115 mm. You can cut and more, I specify the minimum required side of the square. In the center we make a hole 6 mm. In the corner of the reflector, we also produce a 6 mm hole for attaching an antenna. Then take a small plastic tube or tube from any dielectric. Cut from it 13 mm and, using thermocons, fasteners, the resulting detail, in the center of the reflector, so that the openings of the reflector and the tube coincide:

We produce a wire with a solder vibrator in the central hole of the reflector. With the help of thermoclause fix the vibrator. Before installing well, consider the installation location. The antenna needs to be placed so that the vibrator is located horizontally. Also, it is necessary to turn the vibrator in the direction of the receiving tower. Antenna is better to arrange indoors. If you plan to use outside, it is worth taking care of the antenna waterproofing. I secured the antenna on the window of the window on the street. So that less rain and snow fall on it, secured it at the top. Thus, it is, as it were, under the visor:

Do not forget to drill a hole in the window frame and turn it into it.

Step 4 Connect an antenna to the modem.
At the end of the wire, install the SMA MALE connector. Middle contact must be soldered, the outer braid is fixed with a metal tube, insulating a heat shrinking or tape.

Exterioryota antenna - a simple solution to a big problem

The Yota amplifier, as you can guess from the name, is nothing more than an external (installed outside the housing) receiving-transmitting module, made in the form of a street or room antenna, compatible with the modem and routers manufactured under the Yota brand. It assumes the functions of their regular low-power antennas, increasing the integrity and data transfer rate.

Wireless Internet from Yota is such a thing ... often it does not reach the speeds promised by the operator. It is not surprising that the Yota amplifiers enjoy the population with such great demand, which is not just remained unchanged over the years - it is steadily increasing. After all, for many, the amplification of the Yota signal has become a real "headache" - a problem that is seen intractable.

However, exactly until they percade the electronic store site, where you can always buy an antenna for Yota, and not just buy, but this is the most profitable price in the city! The solution of many years of Internet problems, as practice shows, probably not take you not only much time, but also money. Not so serious was this problem if you figure it out ...

How not to make a mistake with the choice of antennaYota.

However, it is not necessary to assume that it will be able to allow it absolutely any antenna for Yota, which you purchased on the occasion of the subway. Such purchases are rare when it turns out to be successful, and therefore you do not need to lay great hopes on them ..

What do we mean by the word "good"? This is such an amplifier for Yota, which will be the same efficient and in the city feature, where the neighboring buildings are closed by radiation of base stations, and beyond where the base stations are strongly removed. Problems with the use of wireless Internet arise everywhere, but you no longer need to worry about them - they don't touch you now!

Having preferred an electronic store site, you are guaranteed to get an effective amplifier of the Yota signal, since others are simply not in our assortment. All you have to do is to decide on the technical characteristics that directly depend on the technical characteristics of the Yota device you use the (modem or router).

Objective signs of a good antenna foroTA

Not least materials from which are produced by our amplifiers for Yota have not latter. External antenna, even if it is used in the room, and if in the open space - so in particular, should be made of high-quality weather-resistant, but at the same time do not create interference materials. Otherwise, the Yota amplifier is not that will not provide due efficiency, but will not work for a long time.

Distinctive features forYota.LTE

External antennas designed to enhance the Yota LTE signal (Yota 4G) have become widely demanded relatively recently. The wireless networks of the fourth generation, which came to the major cities of Russia, did not fully, because of which many subscribers were not able to enjoy the traffic and stability of the Connect.

According to its design and the principle of the antenna, the Yota LTE is no different from the antennas intended for use in the networks of previous generations. The difference lies in the data standards supported by it, which are more demanding and to the receiving, and the radiative antenna capabilities, as well as in technologies and devices developed under them.

However, in the same measure as the external antenna Yota, it concerns cable products and connectors used to attach it to the same names and routers. LTE amplifier for YOTA, if it has been connected using low-quality cables and connectors, can lose up to 15% of the received and transmitted signals, thereby crossing all the advantages of its use ...

On the dangers of low rooms for antennaYota 4.G.

But back directly to the Yota LTE signal amplifier. All of them are developed taking into account the most modern achievements in the field of wireless communication and therefore no complaints cause. Developed by many companies from the USA, China and some other countries, because for LTE, if you believe international experts, the future, and for its commercial use - a big benefit!

The situation spoil small producers, who, wanting to make it easier to reduce their products (including Yota LTE antennas), use absolutely unusable materials that are capable of any, even the most brilliant project to turn into a "non-viable freak". Examples of this - thousands. Their lion is made up of Chinese-made antennas, intended for use in conjunction with USB modems.

External antennas for Yota (to enhance the signal of the said operator) are presented in Russia very widely. Buy the Yota 4G amplifier today is not a problem, it is in another - in his choice! The latter is quite difficult to the innumerable manifold of trademarks, among which are extremely little trustworthy. Often the buyer has to choose between bad and ... bad, in our opinion it is unacceptable.

Amplifier for modemYota at a bargain price

Fortunately, you are on the website of the electronic store site, whose clients who have decided to purchase one or another device for Yota (signal amplifier, for example), do not face similar problems. The Yota LTE external antenna bought here will certainly be summarized by providing perfect reception and data transfer regardless of the remoteness from the base station.

However, this is not the only strong side of our antennas to strengthen the 4G Yota signal, - their favorable value also worries many, attracting all new and new buyers to the site. Precisely profitable, but not understated; This, let me notice, not the same thing! With cheap, incomprehensible to whom the antennas we do not have, and you do not advise you!

The same antennas for enhancing Yota LTE, which you can see in the catalog of this site, are sold at the best prices in Moscow, which we rightly call profitable! These antennas were not accidental here - they are made of high-quality metal alloys and modern polymers, with the strictest compliance with the requirements of the LTE standard and the global standards associated with it.

Strengthening the modem signalYota technologyMimo.

A separate word deserve antennas that support MultiPle Input Multiple Output technology (MIMO) that have recently appeared in the external device line for Yota. Mimo-antennas are characterized by a more complete use of the bandwidth-provided capacity provided by the LTE standard, which has become possible due to the separation of the receiving-transmitting device into two parts - accepting and transmitting.

The MIMO compliant Internet signal amplifier for Yota is thus not one, but as many as two antennas that need to be installed so that they do not interfere with each other, creating frequency correlations. Such antennas for the LTE modem Yota provide at least twice the best data transfer rate, and this is no change in the level of standards.

To date, the MIMO signal amplifier for the Yota modem acts best solving problems when using Radio Frequency Channels for LTE Standard. Its disadvantage, and then small, it is considered only the need to set two antennas instead of one, but it is successfully eliminated by the use of frequency selectivity technology (by connecting these antennas in one case).

Your choice - antenna and modem (router) in one set

Antenna for 4G modem Yota, like an antenna for another popular Yota-device - Router, you can buy from us not only separately from the modem itself (router), but also with it. After all, the electronic store site sells not only a variety of antennas, but also other devices designed to work in the Wireless network of the Yota operator, as well as accessories for them.

Buying a Yota-modem with an antenna is, without any doubt, the right decision. Antenna, you will have to purchase anyway - not now, so then, having spent annal amount of time on her selection of the modem characteristics, which is not at all as easy as it may seem at first. It is better to do this in advance by buying a modem of the Yota operator with an antenna in a set! So, by the way, not only more convenient, but also cheaper.

Note - Antennas with the built-in Yota modem from us are also sold. Such antennas are predominantly indoor (intended for operation in rooms with normal humidity and temperature); They are optimal for use with laptops and tablet computers, at home, at work, outside the city, on the road - no restrictions!

Sale Antennas for ModemYota and not only

We are engaged not only by selling, but also by installing Yota antennas. This service is one of our most popular: it took advantage of more than 80% of those who have bought these very antennas at one time. Considering how well the specialists of the electronic store site are dealt with Yota's devices, the installation of the antennas does not seem such a challenging task for them.

Here you need to clarify that they are far from always with each other compatible - modem Yota and external antenna. Many modems of this brand, as well as many of its own routers, do not have connectors for connecting such antennas at all, which pushes their owners to experiment with the soldering iron. How can all this turn into? In addition to losing guarantee on the device, nothing ...

With us you can not only purchase modems and routers, but also modify them by adding the possibility of joining the external Yota antennas. Buy alarm amplifier and not to be able to connect it to the modem - this is, of course, unpleasant, but not so much to spoil yourself. Just contact us, and we will eliminate this annoying error of modem manufacturers.

How to choose an antenna for Yota?

Yota's communication refers to the 4G generation, it uses a high-frequency signal of the LTE 2600 range, which is by its nature (a small range of distribution, attenuation during walls) is similar to a WiFi 2400 MHz signal. The main advantage of Yota is a high speed of reception and data transfer, the main disadvantage is the small range of base stations (usually up to 5 km). Fortunately, eliminate this disadvantage is called LTE antenna for Yota.

In the 4G standard, the technology is implemented in the reception plane and signal transmission, so we recommend two-detachable 4G MIMO antennas to enhance YOTA. Mimo antennas show speed gain (especially upload) compared with single. It should be noted that double antennas are more expensive in the manufacture, and also require two cables to connect to the modem / router.

This section contains LTE 2600 single-disconnecting antennas:
So and various double MIMO antennas :, LUNA 3G / 4G BOX, MIMO

Many users who acquired a mobile 4g-bond, have already noticed that the market does not particularly induce the buyer with accessories for LTE devices. It is especially felt by the lack of an assortment in the antennas market to enhance the portable modem signal. However, with a detailed study of products in the corporate segment, it is found that the necessary devices are on sale, here only their cost several times higher than a worthy 4G-modem.

The focus of this article is a system for amplifying a signal produced by Yota. Antenna is presented on the market with several modifications that are present in different price segments. The reader has the opportunity to get acquainted with interesting products, learn their technical specifications, and also find out how from the submitted means you can create a portable system to enhance the signal.

Market leader

Undoubtedly, among all producer products there is a model that is awarded the title "Best Purchase". Yota (Antenna) Connect 2.0 is considered to be a sales leader in the domestic market, because the manufacturer managed to combine many useful features in one device. First, we are talking about mobility - the portable antenna has not only small sizes, but also a folding design, allowing the user to transport the device in a backpack or bag with a laptop.

Convenience of connection also not left unnoticed owners. For the LTE modem on the antenna housing there is a special USB slot to which the mobile network device must be connected. But the modem is connected to a laptop or computer by an extension agent, which already comes from the signal amplification system.

For everything you have to pay

It would seem that the Yota antenna with a built-in modem has no flaws - buy a set and enjoy broadband Internet. However, in their reviews, users express dissatisfaction with the fact that the signal amplifier works only with the same device. That is, it is impossible to buy such a convenient and portable antenna for other modems (ZTE, MTC, etc.), since the gadget will not work at the hardware level.

The way out of the current situation, of course, is. The USB receiver on the antenna can be disassembled and neatly a soldering iron liquidate the Yota controller. After that, it is necessary to connect the wire with a copper cable to the controller with the antenna housing. True, the signal power after chip seizures deteriorates, but such a solution is still better than the use of a modem without an amplifier.

Directional action system

Ethernet wireless antennas have lost their relevance in the past decade, because many providers are easier to stretch the cable at a distance of 30-60 kilometers, rather than selling expensive equipment aimed. But facing the LTE poor coating, the manufacturer had to take advantage of the forgotten technologies. Yota with the strange title Hite Grid copes perfectly with the signal amplification, being from the tower at a distance of 20 kilometers.

Yes, such a device is considered stationary, as it is dimensional and cumbersome, and the design is not suitable for transportation. But here you can already decide the user that it is more important to him - a decent transfer rate or convenience. A feature of such an antenna is the fact that there is no binding to the provider or the manufacturer of 4G modems.

Above, faster, stronger

But the parabolic systems did not fit in the domestic market. The thing is that Russian-speaking buyers are able to notice the difference between the satellite signal and the 4G network work in which the Yota modem works. The external antenna, made in the form of a plate, undoubtedly attracts attention to the appearance, but when it comes to the quality of the signal, the device will surprise the user with nothing.

Antennas of aimed action in the form of parabolic plates are offered by the Baltic, Polish and Chinese manufacturers. Externally, they are almost identical and differ only in the diameter of the disk and the title. On the domestic market, only the Sky Flex brand can be recommended from the domestic market, which is able to demonstrate the signal amplification. When buying, it is necessary to pay attention to the fact that the company's logo is not in the form of a sticker, but painted on a plate. On the table with the serial number, the Sky Flex Yota inscription is duplicated with print.

FEATURES OF MONTAGE

All antennas aimed action has one unpleasant feature - the high-frequency cable from the receiver to the modem is very expensive. It is not difficult to guess that all owners of the Yota gadget is the connection of the antenna installed on the roof of the house will cost weekly. You can solve the problem with the acquisition of additional accessories to the signal amplification system.

If the Pigtail communication cord is used to connect the modem, you can install the modem (securing and protecting and protecting from moisture) directly on the antenna housing. And connect to a mobile device or computer to provide active (10-30 meters). Alternatively, many users will use in the form of an extension.

Alternative to folk craftsmen

Many users assure in their reviews that the homemade antenna for Yota is used. With your own hands to create a device, they made the manufacturer himself, who set the overestimated price for its products. The role of the directional system can play a regular television antenna, known in the people as Polish. To do this, disassemble the modem and disrupting the wires from the built-in amplifier, connect them to the television antenna terminals.

In fact, it is possible to replace the Yota accessory (antenna) by any girlfriend that can enhance the signal. Even a regular piece of reinforcement or copper cable will suit the antenna. The only thing you need to know the owner is the principle of the receiver and contour, which should not have a chain.

From the subwoofers

The usual tin can or colander will fit as an alternative to an antenna of aimed action can be collected in several ways: using the active contour and on the principle of direct visibility. The easiest solution in extreme conditions for any owner of the mobile device and the modem can be the use of a conventional aluminum container from carbonated water or beer. The bank is washed, it is cut off with a knife and a modem connected via the USB interface, fixed in the opening from the reverse side.

An advanced system using an active circuit requires the owner to disassemble the modem and output two wires from the built-in amplifier. Also, the designer will need an empty pack of cigarettes, a nail or large cross section. It is necessary to break through the cigarette pack and secure on a metal hat one end of the cable derived from the amplifier. The second cable is connected to the circuit contour. The pack must be inserted into the jar so that the metal does not come into contact with the circuit's contour. Such a simple mechanism can take a 4G signal even at a distance of 20-30 kilometers.

Finally

As practice shows, options to solve the problem with amplification of the signal for the LTE device a lot. People with unlimited financial opportunities will suit the solution from the manufacturer Yota. The antenna will cope with all the tasks and will provide the owner of high-quality communication. Do not get upset and users who have a limited budget - to make a directional antenna from the primary means is very easy, only small knowledge of electrical engineering and desire are needed.

The Yota operator provides its subscribers only wireless Internet. Most of the difficulties of users are connected with this. If the wired technology allows you to achieve a constant high speed and stability (only accidents at stations can be attributed to exceptions), then many factors affect the wireless network.

Let's figure it out if antenna is needed for Yota, and how it can affect the speed and stability of the connection.

External antenna amplifier for modem Yota LTE: need or not?

To understand the question, you need to evaluate the features of the Internet at different times. In the event that the network holds stably, the speed does not fall, then the amplification of additional devices will not be required. But in what cases then you should get an amplifier?

Think about buying an amplifier or independent manufacture in the following situations:

• constant signal loss at different points of the house;
• speed \u200b\u200bdrops;
• use a large number of devices connected to the Internet through one router / modem.

Users have a choice: to buy corporate equipment, or try to strengthen the signal with your own hands. Let's talk about each method more.

Options for amplifiers

If your task is to provide the Internet a large number of devices, then you will fit the Yota B315 Internet Center with an external antenna. The device itself allows via Wi-Fi network, and the connected external amplifier will increase the stability and reception of the signal.

On the official website you can purchase Yota B315 for 6900 rubles (cost in Moscow and the region). If you do not need an Internet center, then you can do the closer with the external antenna connector - LU150 Lite. Connect the external antenna to the Yota modem only with a special port or USB connector.

Before buying, carefully examine the characteristics of one and second device - the availability of ports must coincide. Connecting the device to the modem is carried out through the pigtail - adapter from the standard antenna socket to the specific connector.
If not sufficiently developed, and the modem is constantly switched to 3G, then when choosing an antenna, this moment also needs to be considered. The device must support both technologies. Otherwise, you will have to buy two antennas.

Strengthening the signal with your own hands

External antennas for the Yota modem, 4G LTE signal amplifiers cost a lot of money. Most users cannot afford to acquire expensive devices. However, it is not necessary to despair in such a situation - you can try to make an antenna for Yota with your own hands.

You can make the amplifier from the remedies. The most common example is a saucepan, aluminum pelvis, foil. The modem is placed inside a pan or a cardboard box, glued foil. Next, the design is attached in the place where the reception of the signal is higher. If you are going to fix the homemade construction on the street, then take care of the protection of the modem from external influences (rain, frost and so on).

Also, an ordinary satellite antenna is suitable for enhancing the signal. You must attach a router to the converter, then send the design to the side of a good signal reception. If neither you have no other, then use the copper wire and foil textolite to create antenna Harchenko. More detailed instructions and scheme for it you can free download from the Internet. With the help of our tips you can do without large spending on the amplifiers.
