The Teflon and silver connectors I have used absolutely will not stay tight. Now it says Amphenol or Andrews or it doesn't go to the repeater site. Yes they "shor do solder purty", I am still wondering about the magic you used to get the aluminum soldered. Can't imagine that's actually - well you get the picture.
