80m HF 6000W Band Pass Filter. Designed to last.

High power 80 meters 3.5 – 4 MHz band pass filters for EXTREME BIG GUNS

Bandpass filter is perfect for a multi-station environment like special events, field days, and portable operating to protect receivers from excessively strong out-of-band signals. Our 80-meter filter is designed to have an extremely low loss from 3.5 – 4 MHz (80-meter band) and it is less than 0.1 dB! Out-of-band interference is extremely suppressed. The filter is ideal to be on both reception and transmission. The 80-meter bandpass filter is declared at 6000 W, but the filters are designed for more power than presented. The Bandpass filter is placed in a powder-coated aluminum box. Silver-plated SO239 connectors and excellent filter design enable extremely low losses through an 80-meter band and high attenuation of out-of-band signals.
