Just be aware that the PL259/SO239 series of connectors is not waterproof,
not even water resistant. Don't use them where rain and such can
contaminate the coax.

That's why I use a lot of "Liquid Electrical tape". It works very
well. Two coats...Let one cure, then add the second. Coat both sides
of the SO-239 "AFTER connecting the PL-259"

You can also "flood", the PL259 with a silicon grease such as DC4
compound which was made to water proof spark plugs on B-17s and to
keep them from arcing over at altitude. Stuff works great, BUT
nothing will stick to where ever it touches.

I typically use "N" connectors, but they are expensive compared to the
UHF (pl-259/so-239) connectors. I have blown out a couple of N type
barrel connectors to the feed points on the 75 meter slopers. That
shouldn't be a problem on receive.

Purchase an SO-239 chassis connector. Get one that has 4 small screw
holes (one in each corner. I've forgotten the length of a quarter
wave on 122.8, (I'd have to look it up some where around here)

Put a PL259 (male connector) on the end of the coax that goes to the
antenna. Put what ever is required for the end that goes to the
radio. I use PL-259s on each end with an adapter to fit the radio.
