How do you build a community RX antenna system without a window filter? Multiple cavity filters a la a "reverse combiner"?

Many places got real crazy with IRLP and echo link paths. Around here on 440 the input band is fairly well regulated. Any TX that shows up in that band at a comm. site is highly frowned upon. We did have one "temporary link" show up at one site that was pretty much in the middle of the input band, only 140 kHz away from an input I maintain. However, it never bothered that input in any way so we let it slide. Bob NO6B
