20 meter 6000 W High Power Band Pass Filter
High power 20 meter 14 – 14.35 MHz band pass filters for EXTREMELY BIG GUNS.
Band pass filter is perfect for multi-station environment like special events, field day, portable operating to protect receivers from excessively strong out-of-band signals. Our 20 meter filter is designed to have extremely low loss from 14 – 14.35 MHz (20 meter band) and it is less than 0.12 dB! Out-of-band interference is extremely suppressed. The filter is ideal to be on both reception and transmission. The 20 meter band pass filter is declared at 6000 W, but filters is designed for more power than presented. Band pass filter is placed in a powder-coated aluminum box. Silver-plated SO239 connectors and excellent filter design enable extremely low losses through 20 meters band and high attenuation of out-of-band signals.
