Simple - use something better than PL-259's:
I mainly use N connectors for low loss/high power and BNC for low
power inside the shack connections. I also have TNC and sma connectors.
Most connectors need a 1/4 turn beyond finger tight for reliable
connections. Sure cure for loose connectors is heat shrink over
them. Not only seals from wx but also loosening due to vibration.
Want to see what vibration does? Install a radio in a D8 cat without
some kind of vibration damping. I did long ago, and the Motorola
100w VHF radio was a cabinet full of loose parts after 8-hours
running of the cat. Wonder why military radios are full of glyptol,
or completely potted in plastic?
