They are very expensive, some in excess of $100 each, but they have very low loss, and they are sealed well against WX. When I order baluns or switches, I always specify that they must be made with 7/16 DINs, and I have never been disappointed with their performance.
I'm trying to understand, Alan, so could you please. define "performance," and please tell us in what application, at what frequency, and how you actually KNOW their performance.
Unless you're using them in critical small signal applications at UHF, I'd call that a very poor allocation of financial resources. I can think of many better ways to spend $100. The loss through a quality PL259 or N connector is negligible in most real world applications, and there are simple and effective methods of waterproofing them.
BTW -- the nicest male N connectors I've found for RG8/213-sized cable are made by Andros Engineering, a machine shop owned by a ham. They're a 2-piece connector, with both center and shield rigidly assembled to the same part to which you solder both center and shield, then screw the outer shell onto it. Very easy to do, and zero possibility of shield migration.
