OK, Let's talk about the isolation charteristics of just transformer splitters
and REAL HP/LP duplexers. With splitters, I think you are subject to mismatch
isolation problems if the loads are not matched. Same with Duplexers, but most
desighs allow for some matching, at least the ones I design do.

And don't forget that the isolation spec assumes a perfectd 50-ohm
termination on all ports. For example if one of the ports is seeing a
load with a 10 dB return loss, then the isolation will be no better than
10 dB.
