Two failings of off-brand UHF connectors is the machining of the
threaded surfaces and the female center pin cup. Off brands don't
have the thread precision that Amphenol has. There's a risk that the
female center pin holder won't grip well. When shopping at hamfests,
bring a UHF male with you and use it to see how hard the fingers in
the jack cup grip the pin. I've burned up jacks that were junk before
I learned this. I have not found an Amphenol that didn't have a tight
grip unless it was misused (jamming a banana plug into it etc.).
