40 meter 6000 W High Power Band Pass Filter

High power 40 meter 7 – 7.3 MHz band pass filters for EXTREMELY 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 40-meter filter is designed to have an extremely low loss from 7 – 7.3 MHz (40-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 40-meter bandpass filter is declared at 6000 W, but the filter is 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 40 40-meter bands and high attenuation of out-of-band signals.
