430 - 440 MHz 2500W -0.06 dB Transmitting - Receiving Band-pass Filter with 7/16 DIN connectors

Filter is completely the same as 1000 W version except connectors (7/16DIN - "N").

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.
 

This is ultimate 70cm bandpass filter.

Measured data with HP8753ES network analyzer full two port calibrated.
