Note:
1. Since it is located in the UHF frequency band, there are certain requirements that the input and output are required to be coaxial cable with 50 ohm impedance.
2. Due to the large output power, do not connect the antenna directly to the output port of the power amplifier. Please use a 50 ohm coaxial cable of no less than 2 meters to connect to the antenna.
3. This power amplifier is a one-way amplifier that can only work in one direction. It cannot be used on devices that have signals such as B.
as a two-way data transfer or walkie talkies. If there is something you do not understand, please contact for confirmation.
