FLEX PGXL Linear Amplifier RFI Kit - Single/Dual I/O Options
PURPOSE
These kits are designed to choke common mode currents going into or exiting from your amplifier cables.Filters are supplied for the RF In, RF Out, Relay Cable/control lines, and AC power line.Use of the filters often helps cure SWR problems between amp exciter and amp and between amp and antenna tuner or direct to antenna.The AC power line choke helps keep common mode current out of the power line which could cause interference to other devices connected to the same power line if not suppressed.
USE
Standard kit for amplifiers with single input, single output, relay keying and AC input
