Note: 1. Because of UHF frequency range, input and output cables have certain requirements, input and output must be 50 ohm coaxial cable. If you connect it with ordinary wires, it may not work properly, or may cause abnormal phenomenon such as low power or self-exciting. Please do not connect the antenna directly to the output port of the power amplifier because the output power is large. To avoid strong signal interfering with normal operation of the power amplifier, please use a 50 ohm coaxial cable at least 2 meters to connect the antenna. The power amplifier output must be connected to a 50 ohm pure resistance load. For antennas, the stationary wave must be less than 1.5 in order to ensure the transmission distance and safety of the power amplifier.
