Dear,Plz send us an inquiry with product title if you be interested with it ,And we are willing to provide you with better service.

The antenna switch is specially made for HAM. The effect is excellent, the insertion loss is low, and the price is only about 30% of imported goods. The performance is not inferior to imported goods at all. It can be used in various radio equipment such as UV section car station, hand station, shortwave station, SDR receiver, FM radio receiver system and so on. The method of use is very simple, just flip the switch to access one of two options. There are 2 common connection methods, see the baby introduction picture for details

Used to connect 2 antenna systems to a radio station. Note: The two antennas are essentially not connected to the radio at the same time, but only one antenna can be selected to be connected at a time through the switch. For example, you can equip the radio with an omnidirectional fiberglass antenna and then a directional Yagi antenna. Switch according to the communication needs. It is also possible to connect two Yagi antennas to aim at different directions, and to switch antennas in different directions through the antenna switch, the signal strength of the radio will be different, so that the signal direction can be easily distinguished. In short, there are many ways to play with dual antennas, and you can study them slowly. If equipped with multiple switches, more antenna switching options can be achieved.

Equip one antenna for 2 radio stations. Note: This method is not recommended! It is only recommended for 2 receivers without transmitting function to connect using this method. Since the launch function is risky, it should be used with caution and bear the corresponding consequences. Therefore, this connection method is not recommended. Because only one radio is connected to the antenna at any time, and the other one is not connected to the antenna. Therefore, you must confirm the power-on and launch. In addition, this method can also be used for home decoration wiring. For example, set up an antenna from the roof and a feeder into the room, and place a radio station in the living room and bedroom (the indoor feeder is planned and arranged in advance), and you can use the switch at the feeder end of the house according to the location of the radio station. Perform antenna signal switching between different rooms. It is very convenient.

In addition, because the received signal strength is different, there will be a problem of inductive signals. That is to say, when using a connection method of connecting two radios with one antenna, no matter which position the switch is set to, the radio without the antenna can still receive the antenna. The received signal is a normal phenomenon caused by signal induction. It is like taking a handheld without an antenna and transmitting with another handheld beside it. The machine without an antenna can still receive the signal. But if you want to transmit, you must switch the switch to the radio station to which the antenna is connected. In addition, if two radio stations share the same antenna connection, if one of the radio stations transmits, there will be a strong induction signal through the nearby space, feeder, switch and other connecting parts, which may be induced to the other device, which may affect the other device. Produce unpredictable effects and damage, so be careful to conduct experiments on the size and duration of the transmission power. The equipment damage caused by the connection method of connecting two devices with one antenna shall be borne by yourself.

Because the switch direction and port access of different batches of products are not necessarily the same, use a multimeter to measure and confirm the corresponding relationship between the switch handle direction and the two ports connected before use, and make a mark. For ease of use. Usually the switch is turned to the right, the interface on the left is connected, and the interface on the right is disconnected. Friends who need a matching feeder, please go to the store to purchase and consult. We have a variety of feeders and connectors to choose from.
