TV antenna power supply 1 output 500mA The TV antenna power supply must be combined in systems that have a pole amplifier. This TV power supply must be connected to the amplifier via a coaxial cable, which transfers the electrical voltage necessary for the operation of the 'amplifier. Another important feature is the output power in mA, a fundamental parameter for the choice of the TV power supply. There are power supplies with a maximum output power of 200mA on the market. Our product has an output power of 500mA suitable for any type of amplifier on the market. Technical characteristics 1 Input 1 Output 12V DC 500mA
