70 cm 430 – 440 MHz 2.5 kW -0.06 dB Transmitting Band Pass Filter

With its extremely low insertion loss, this filter could be used as a transmitting and receiving filter in line with the antenna.

– As transmitting to suppress any harmonics from 70 cm up to 2.5 kW linear amplifiers.
– On the receive side before LNA to protect receive performance from any HF, FM 2 m, 220 MHz, or 23 cm strong stations.

The filter is completely the same as the 1 kW version except for connectors (7/16 DIN – “N”).
