160 meter 4000 W High Power Band Pass Filter for 1.8 MHz Band
High power 160 meter 1.8 – 2 MHz band pass filters for 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 160 meter filter is designed to have extremely low loss from 1.8 – 2 MHz (160 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 160 meter band pass filter is declared at 4000 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 160 meters band and high attenuation of out-of-band signals.
In-band insertion loss less than 0.12 dB (1.8 MHz – 2 MHz). Second harmonic is suppressed by more then 40 dB! Measurements on assembled filter were done with HP8753ES full 2-port calibrated.

High power Band Pass Filter 1.8MHz Power Deteriorating Chart.
Filter has low insertion loss and low SWR across an entire working band. Therefore, we design with emphasis placed on maximum possible rejection of second harmonic energy, so our filters are carefully projected to fit approved frequency range. In conclusion, improving filters and making them better is our passion. Fine engineering can be noticed and our products, usually exceed our competitors in more then a few things. Each HF band pass filter is handmade and configured to match the desired characteristics. Also, before packing we check the filters again to ensure maximum quality.
