This antenna amplifier has a gain of 22dB for frequencies from 10MHz to 150MHz (AM / FM band). The included metal housing ensures that there is less interference on the line during amplification. The amplifier is supplied as a kit, which means that you have to solder the parts on the board yourself to build a working amplifier.
Power supply: 12V to 15V / 3mA
