Hi Chuck and the group -- Thanks for this input -- It has been well known for years that the cheapy connectors that most hams purchase won't cut it on repeaters. There are only a couple of manufacturers that I will purchase or that we will purchase in the shop. AMPHENOL silver plated/teflon being one type.
As the BNC connectors, well there is many schools of thought about this but good connectors work fine. Heck TX/RX uses them all the time without issue on their duplexers. I also question why we keep hammering on UHF when, we use good connectors, they are still getting a bad rap? UHF has strength and as long as they are treated well they serve well. Where "N" connectors shine is in wet environments, and where constant impedance is a must. As to coax, RG-8 (214, 213) is not a requirement, use teflon RG-142B or RG-223! Both are very good candidates for repeater and duplexer use. Constant impedance, low loss, good/excellent shield - less leakage (or crosstalk), and easy to work with. Certainly, a plus.
