30 meter 3000 W High Power Band Pass Filter

High power 30 meters 10.1 – 10.15 MHz band pass filters for BIG GUNS.

Bandpass filter is perfect for multi-station environments like special events, field days, and portable operating to protect receivers from excessively strong out-of-band signals. Our 30-meter filter is designed to have an extremely low loss from 10.1 – 10.15 (30-meter band) and it is just 0.18 dB! Out-of-band interference is extremely suppressed. The filter is ideal to be on both reception and transmission. The 30-meter bandpass filter is declared at 2000 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 30 30-meter bands and high attenuation of out-of-band signals.

WARC bands.

The WARC bands are three portions of the shortwave radio spectrum used by licensed and/or certified amateur radio operators. They consist of 30 meters (10.100–10.150 MHz), 17 meters (18.068–18.168 MHz), and 12 meters (24.890–24.990 MHz). They were named after the World Administrative Radio Conference. This WARC filter can be used for power up to 3 kW, but it is also perfect for less power. Since its low loss, the 10.1 – 10.15 MHz WARC bandpass filter is perfect for transmitting as well as receiving.
