I use a single PL-259 for all the transmitting antennas as a lightning
disconnect. I can attest to the fact that trouble ensues if I forget to
tighten it with the pliers. I crashed my computer during the contest
today. Twice, before I caught on.

No, a bit paranoid perhaps but I disconnect the rig entirely,
including p/s cable. It's not too bad since I'm mostly a CW operator
and don't usually have a lot of other peripherals, SDR, computer, etc.
connected to the K3.
BTW, I don't trust the Amphenol name particularly after getting a bad
plug that wouldn't thread correctly (only realized after soldering the
thing on the coax and trying to use it. Arggh!). Amphenol is offshore
product now.

Drew and all,
I have changed the subject line to something more akin to the current
discussion.
Have you considered adding a coax switch? Turning to switch to an
open position (or better yet to a dummy load) when the radio is not
in use will provide protection and is a lot easier than removing the
connectors.

FWIW, I use NO-OX-ID contact grease on my PL259 connectors. This
allows very tight snugging by hand, no need of wrenching.
During lightning season I frequently connect/disconnect my rig and
tuner cables. The fine film of lube on the connector threads makes a
big difference. Without it? A real PITA, not to mention wear and
tear on the the SO-239's.
