Antennas for portable radio stations. Antennas for portable radio stations Outdoor panel antenna 400 470 MHz
Greetings all radio amateurs and not only. Today I decided to tell about one of my enough useful purchase.
External antenna for walking on a car, with magnetic fastening.
This antenna is useful to everyone who wants to improve the quality and range of reception \\ transmission of speech in the races installed in cars.
Also in the review I will tell you and show how cheap and simply connect similar autotennas to portable manual tagging type Baofeng, etc.
We read further.
One of my long-standing wish is the purchase of a car radio. But while I use the Wouxun KG-UV8D wagon (Plus) in the presence of my insurance.
In the summer, the family and I often go to vacation for 2-3 cars. Everyone has long been there several sets of racies. (I have,) in relatives are simple for communication, but normal Baofeng 777s.

And we usually keep the connection between yourself through negotiations through the radio. It is more convenient than cellular communication. First of all speed. He took the radio, pressed the button and say. No need to wait for a dialing, you do not need to look for where catt leaves, you do not need to pay for this very connection.
Communication usually occurs within the limits permitted everywhere, PMR frequencies. But sometimes it happens that even within visibility, communication is lost for various reasons. And partly in this is the shielding of the car body. So, to fix it, as well as to increase the range of communication, I decided that I simply need an external antenna into a car.
I ordered on the BG simply because I have in the city prices for similar antennas are simply cosmic.
Also, the choice fell on a magnetic antenna due to the fact that it is sometimes necessary to remove the antenna from the machine when the car remains in the yard for several days. Well, the ability to rearrange this antenna to another car will be very useful.
The site of the antenna shows the following characteristics:
Gain: 2.5 / 3 DB
Max.power: 50 W
Impedance: 50 OHM
Connector Type: UHF
ANTENNA LENGTH: 9 CM
Cable Length: 5 Meter
Frequency Range: VHF136-174MHz / UHF400-470MHZ
Judging by the reviews of people, the antenna is quite normal. Yes, and the price is available. Therefore, the order.
Delivery lasted for almost a month. In the mail received a package, inside which was such a drill:
Inside the antenna itself, and the magnetic stand with 5 meter cord:
The device of this antenna is pretty simple:
From the bottom side, the magnet has a sticker from the material similar to the self-keys. I think it is pasted to protect the paint coating of the car:
Sizes of the 9cm * 4cm stand.
The side of the stand is 5 meter cable with a standard UHF Male connector:
The antenna itself is a cylinder, the size of 9cm * 3cm:
Top plastic. Metal bottom. There is a sticker with information in which ranges This antenna works:
The antenna connector is also standard UHF MALE:
Antenna assembly:
I will use this antenna together with Wouxun KG-UV8D Filing (Plus):
Since this radio the antenna connector is another, I additionally had to order an adapter on eBay. We have these adapters and rather than about 5 dollars. In my case, you need an adapter such:
With him and connected wiring, the radio looks like this:
Note. If you want to use in the same scenario of Baofeng production, then you will need to buy a slightly different adapter. It is called like this:
(I also ordered this adapter, but not yet received)
Now about the installation.
Since the antenna is planned as a removable, I just put it on the roof closer to to go, and the wire stretched straight through the trunk:
If necessary, open the trunk and remove the antenna inside. And in the cabin we are already folding. In the unfolded state, the wire is launched along the passenger side under the armchairs of the rear row, the middle row and goes under the front passenger chair. And there already hits the radio, and the radio itself is molded into an ashtray, which is never used according to its intention. But it has a comfortable lid that holds the radio:
In such a form, the radio is always at hand. She can be used as a driver and a passenger sitting on the front chair.
It is certainly less convenient than the car with remote tangent, but while we use what is. Yes, and it is possible to buy a tangent for $ 3-5. I think about it.
Well, it concerns the main purpose of the purchase. Improved communication quality. And it really is. While I do not have a KSV meter, and I'm more than confident that the antenna is preferably tuned to my car specifically. A recent fishing trip by two cars showed primarily a reduction in noise and improving the quality of the receiving signal. All negotiations were conducted at a frequency of 446.08125MHz.
What about the range is also noticeable improvements. I was able to catch the VHF station broadcasting about 35km from me. I have never accepted this station on a simple elastic band. And this means that there is an improvement.
Conclusion:
A good antenna on the magnet, which can be used. I personally remained satisfied with the purchase. I can safely recommend this antenna. Despite the fact that I did not give any accurate measurements in the review, my experience has shown that the improvement of the reception, compared to the staff antenna really is. As this antenna behaves with a more powerful automotive radio, I can not say. But I think it is quite normal.
At this review finish.

Here are presented various antennas of the range of 400-470 MHz for the racies of various manufacturers. They are valuable in that they can be used for licensed ranges: 433.075 - 434.775 MHz with a limitation of power up to 0.01 W and 446.00625 - 446.09375 MHz with a limit of power up to 0.5 W. It is allowed to communicate radio amateurs, taxi drivers, craners, truckers, etc.
Despite the same frequency characteristics, the antennas differ. Here are some examples of what you can get when choosing:
- Alinco EA-87 is an antenna with a central frequency of 4400 MHz with a BNC connector;
- Anli AT-5R VHF / UHF, in turn, works in two ranges, is made of stainless steel, and its setting is performed by trimming the pin. The device has high wind stability;
- COMET CHL-250H is installed in a magnetic base with PL-connector. Its length is 96 cm, the maximum power is 200 W, and it also works in two bands: 144 and 430 MHz.
We can also help you if we need outdated or removed from the production of an antenna model.
We will be happy to advise you on the range, compatibility and characteristics of these antennas. Call!
The external antenna for a portable radio station is one of the most sought-after positions in the product catalog of the online store radioExpert. Traditionally, portable devices are equipped with shortened antennas. This is because it is pursued by the goal to achieve the most acceptable parameters of the device itself. Typically, such elements have a length that varies in the range of 11-20 cm. Thus, the dimensions are saved, but the signal efficiency suffers.
Today it is proposed relatively cheap to buy antennas for wearable radio stations. Firms-manufacturers specialize in the release of auxiliary elements and accessories. The market features companies with world name Kenwood, Yaesu and others.
Depending on the selected position, the characteristics vary. Before ordering and buying products, you need to explore:
- antenna type;
- brands of radio stations that are suitable for this or that model;
- the frequency range of the active antenna for portable radio stations;
- connector type.
Traditionally, the element is configured by the presence of an instruction where you can learn all the rules and characteristics even more detailed. The cost of products is available for all radio stations.
What are the antennas?
Traditionally, mobile radio station antennas appear in the form of a spiral, which is closed by a polymer shell. It is placed on a dielectric rod that may bend.
It is important that any antenna for a portable radio station is absolutely steadily responding to the impact of the external environment. The convenience and practicality of its operation is complemented by the possibility of ensuring high-quality, uninterrupted communication. The price is really acceptable, but before buying a particular model, will correctly make the selection, having studied the section with the characteristics of the radio station, which is expected to subsequently install an additional remote mini antenna.
Sales are carried out for residents of Russia, as well as CIS countries. We propose to deliver antenna for wearable radio stations. Conditions and speed depend on the location of the recipient. Acquisition will cost inexpensively, and practical benefits are essential and meaningful for those who cannot do without a special device.
