Antenna for walkie-talkies: types, parameters

When buying a radio station, the question ofHow to choose antennas for a walkie-talkie. In this article, we will look at the types of receiving devices and the main parameters that should be taken into consideration when choosing such devices.

Существует огромное количество различных видов antennas. They are active and passive; receiving, transmitting and receiving / transmitting; external and internal; pin, figure, flat, etc. Receiving devices must be selected depending on the purpose and location of the installation. For example, if you need an antenna for a walkie-talkie in a car, you must first determine how you will fasten it: either it will be a slotted device, either "magnetic" or hidden. Usually such devices are installed on special purpose vehicles, they are placed inside the roof. True, the latter in this case should be plastic. Mortise antennas are characterized by the reliability of attachment and aesthetics, but also by complex installation. Magnetic devices are characterized by ease of fastening and dismantling, but at high speeds (or when driving under low trees) there is a risk of device failure, which will lead to damage to the cable and the paint layer of the car.

If you need an antenna for the radio, whichwill be in your housing, then you need to decide what is best for you - an outdoor or a room transmitter / receiver. In such cases it is possible to use both pin and figured devices. If conditions allow, it is recommended to install a mast in the yard for receiving and transmitting devices.

В том случае, если вам требуется антенна для portable radio, then you can use two types of devices. The most common are the pin-and-transmit devices. For portable radios concealed wearing is applied to the antenna. This kind is usually used by special services.

Вообще считается, что самая простая и надежная An antenna for a walkie-talkie is a whip. It, unlike figured, has an omnidirectional diagram of propagation of radio waves. Such devices do not require settings and long guidance on the source of the broadcast. Here on such a product we will stop.

It should be noted immediately that when choosing a receptiondevices do not pay much attention to the characteristics of the antennas, because manufacturers indicate there a lot of specific data (for example, gain factors, etc.), which the normal user does not say anything. The main thing is to remember that the longer the length of your chosen antenna, the better. In this case, you have the maximum possible range and quality of communication. The second important parameter is the maximum power of the device. This indicator will be relevant if the radio antenna is used in conjunction with a radio signal amplifier. Therefore, when buying a device, check with the seller for its maximum power and compatibility with the amplifiers.

Here we are in brief and examined what they representare radio receivers and which parameters are paramount. It should, however, be added that for better reception of the radio signal, it is recommended to place the antenna as high as possible, so that it is not closed at home or trees.
