Jim,
I have used a 0.722" ID Fair-Rite p/n 0431176451 mix 31 Snap-It as the
feedline choke (5 turns of RG-58) on my car for over five years now.
All that is protecting it is a piece of 3" ID dual-wall adhesive
heat-shrink tubing. The ends shrunk down to ~ 0.75" so they are not
closed up and are oriented vertically so water drains. It has seen
blistering sun, sub-zero temps, rain, snow and vibrating for close to
100K miles and it is still in one piece and working well.
