This thread had some discussion of adapters and I want to share my bad
experience with some low-cost items, proving, once again, that you get
what you pay for.

I am testing all my adapters and discarding some because the assemblies
are pulling apart with very little force. One manifestation: tightening
the threaded ring on a PL-259 (either cable end connector or adapter)
and having the ring just continue all the way on, separating from the
connector body.

One test for a future failure has been any lack of smoothness when I
rotate the ring while tugging it gently. If it binds, rather than
turning smoothly in my hands, it's going to fail. Also, some of the
cheap connectors are press-fit together very poorly; they pull apart
with only a few pounds of pull.

Most of my early exposure to coax connectors was in and around the US
Navy, where reliable connectors are the rule, so I was a spoiled child.

PL-259's I can handle.
BNC's drive me nuts trying to get a good connection.
I gave up and just buy my cables now.
