Thanks Skipp & Jeff, On the previous incarnation of the portable repeater, we were using a 'vari-notch' duplexer, and it worked quite well, although not quite small enough to fit inside the 720's box.
I can fit 2 of the 5 cavities inside the space where the power supply was, but the other three just won't fit. That's why I was asking about the smaller duplexers. Just trying to make it 'fireman proof' when it gets setup! Think I'll stay with the vari-notch & see how I can package it to resist damage. (it's in a 2 1/4" thick rack panel now). Thanks, Tim
