Often, I am asked to look at radios in my flying friend's aircraft. The
first thing I do is check out the antenna connections. In particular, the
bnc connector. Rarely is it the radio. The bad connectors are either screw
in or soldered. Not had a problem with crimped. I install a crimped
connector, using the proper tool, and the problem goes away.
However ... last year I was using my spectrum analyzer and tracking
generator to align some 2 meter filters. Results were inconsistent. I
discovered that about half of my short bnc jumper cables (which were all
commercial cables using crimped connectors) had losses of up to 2 db. I was
shocked. All of them looked fine.
Conclusion - you can have bad connectors regardless of whether they are
soldered or crimped.
