A power supply used to power antenna amplifiers via C0397 power separators. This type of circuit is used when the amplifier (amplifier system) needs to be supplied with a current of 12 V and up to 300 mA. The standard D0012 power supply can only supply a current of 100 mA. The circuit with separator C0397 is also used in cases where the division of the RF/TV signal is supplied through splitters that do not pass DC voltage, and it is required to supply power to an amplifier placed on a mast or in an antenna box.
