As long as the filters are working correctly, the cable length from the
duplexers to the radios tx and rx does not matter. Having said that, remember
that the shortest length of double shielded coax or HELIAX cable that will
reach without kinks or physcial loads (binds) on the connectors should be used.
This has nothing to do with impedeance matching, but rather cross talk thru
cable leakage. On this same note (and knowing I'm going to stur up a hornets
nest) I strongly advise against using the LMR type cables for ANY full duplex
system. Any double sheilded cable which uses dissimular metals in the 2 (or
more) shields will eventually cause rf noise .
