Package Included:

1 x 315MHz 8W UHF Power Amplifier Module

Please note:

1. Because it is a UHF frequency band, there are certain requirements for input and output cables. The input and output are required to be coaxial cables with 50 ohm characteristic impedance. If ordinary wires are used for connection, it may not work properly, and strange phenomena such as low output power and self-excitation may occur.

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 to prevent strong signals at close range from interfering with the normal operation of the power amplifier!

3. The power amplifier output must be connected to a 50-ohm pure resistive load, that is, it must be connected to devices such as antennas. It must not be unloaded. Unloaded may damage the power amplifier. Please note! The antenna requires a standing wave of no more than 1.5 to ensure the transmission distance and the safety of the power amplifier!
