Now you want isolation, Just keep in mind that the noise floor is rising and what you purchase today will not be the same as if you purchase it in five years. Bigger is always better and at sites today you can't go wrong with going over kill on the filtering. If you get the standard 4" cavity BPBR duplexer. You can have them add a extra band pass to both the TX & RX side for some extra out of band protection. When you get the duplexer add a TX isolator if your repeater does not have one built in like the Motorola MTR2000. Anymore us hams need to keep our stuff cleaner than the commercial guys. For the most part a lot of us do so but there are a few that really skimp and make it hard for the rest of us when dealing with sites. If you decide to go with Sinclair here is one on EBay that looks new and will perform as good or better than the TXRX and is just an option/comparison in duplexers. http://cgi.ebay.com/Sinclair-Q3220C-UHF-BpBr-Repeater-Duplexer-Combiner_W0QQitemZ280251348599QQcmdZViewItemQQptZLH_DefaultDomain_0?_trksid=p3286.m20.l1116 Happy Holidays, Mike
