70 cm 430 – 440 MHz 1 kW -0.06 dB Transmitting – Receiving Band-pass Filter with “N” connectors

With its extreme low insertion loss this filter could be used as transmitting and / or receiving filter in line with antenna.
– As transmitting to suppress any harmonics from 70cm up to 1kW linear amplifiers.
– On receive side before LNA to protect receive performance from any HF, FM 2m, 220 MHz or 23cm strong stations.

Filter is completely the same as 2.5 kW version except connectors (7/16DIN – “N”).
