Dave, have you tried the one-piece Times Microwave LMR
connectors for the -600 size coax ? As long as you
use the proper prep tool and get the strip lengths
correct, there is no solder or crimp required on the
center conductor - you only need to chamfer the end a
bit. Like the Andrew one-piece connectors for bigger
Heliax (7/8 and above), the center conductor is a
interference fit into the pin. Of course, one needs
to add the screw-in piece to the hollow core versions,
but the idea is the same.
My applications are not as severe or wide-spread as
yours, but I have plenty of them "up the tower" and,
so far, so good. I have swept them to 500 MHz and
they exhibit good return loss. I have no idea whether
Times makes one-piece connectors for LMR-400 or
smaller.
