70cm -0.06dB 1000 W Bandpass Filter
430 - 440 MHz 1000W -0.06 dB Transmitting - Receiving Band-pass Filter with "N" connectors
Filter is completely the same as 2.5 kW 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.
The recorded data on the assembled filter with HP8753ES network analyzer full 2-port calibrated are presented below.
