With respect, why not change the subject line. :-)
As it so happens, I just had an SO239 failure today! As I was moving a
cable near my HF vertical, I was suddenly presented with a cable end
with a PL259 still plugged in to the SO239 which should have been in the
antennas connector box. The center pin of the SO239 had a broken solder
joint and the main cause of the failure was that the SO239 retaining nut
had disintegrated in 3 places. The rest of the connector was still in
good condition.
Before anyone comments - this has nothing to do with my possible KPA500
problem, which occurs on a different antenna.

This is going to cause a big sh*t storm :) and about 900 emails before
Wayne shuts it down.
However, having been in RF for a bit less then most of you (only 1974), I
have had connectors fail and not fail in my HF world (60Mhz or less).
No Name ones have worked wonderfully for decades. Amphenol's have failed
in a year. Amphenol T's in a phasing harness seem to fail the most (fell
apart). But, then, who knows who makes them.
What I can say is that there is, based on my personal experience, no 100%
guarantee on any particular one.
Install it. Visually inspect it. Make sure it is clean, dry and
waterproof and a year from now, if it is outside, open it up and make sure
it is still dry.
It isn't eve 'you get what you pay for' any more.
Next, we can have another 200 emails on how to solder a PL259. :)
