Hi Ian,
What exactly is your problem with filtering? It
reads likeIt seems that you trying to achieve a steep reject notch
for your associated Tx whilst rejecting any outside frequency from your
Rx?
Are you suffering desense on
your site?

Any conventional Notch filter can give you in excess of 20dB of

In essence all notch filters are really a band pass-band reject filter

Hi, can someone tell me the correct loop length for a DB4076W duplexer?
I need to be able to tune it from 440-470MHz. This is the 4-can bp/br

I just want to see if I am getting any desense inside the Radio

I actually thought about taking the compressor out of a small fridge

If you have plenty of thermal contact, it should work ok.

You don't have to shout. Be aware that the Stationmaster trademark used by
RFS/Celwave formerly belonged to Phelps-Dodge, which is why some antennas
