Hi
I'm thinking about putting 1 or 2 bandpass filters on my repeater
receiver...got some desense. System is: MSR 2000, VHF 2 meter,
about 50 watts out of the duplexer, 1/2 in hardline, 1/4 in hardline
jumpers, el cheapo antenna (I know, I know), stock pre-amp, etc.
Question is:
1. Is the jumper length from the pass filter to the duplexer or
PA to the pass filter critical?
2. If I use more than 1 filter, is the length of the cable
between the added on filters critical?
3. Will the interconnect cables within the duplexer need to be
changed?
4. Will the duplexer need to be re-tuned?
5. Would I be better off using notch filters as opposed to pass
filters?
I'm at a somewhat low noise site...closest RF stuff is about 200
yards away with the exception of my micor GMRS UHF repeater (50
watts) that's co-located at the site.
Thanks
