Hi Gordon,
Most in my area like the duplexers made by TX RX Systems Inc.
www.txrx.com
I have several sets VHF and UHF in commercial and Amateur use. I have one
set that has been on my VHF Repeater for almost 20 years and has never been
touched and are still on spec. Customer Service is available by calling and
asking for Mary Brown. She came up through the ranks in the factory and can
tune a duplexer as good as anyone and is now taking questions and wants from
the customers.
Good luck.JIM KA2AJH
