What's more, the radio's input power should be within 3.0-8.0W. If lower or higher than the watt, it will not work or be damaged. (2) If you want the amplifier reach the Max output power, it needs the input power reach Max. However, we do not suggest to do so for a long term, because with the Max input and output power, the amplifier loss also reaches the largest, which will decrease the amplifier lifetime!
