Thanks for the great info, GroundUrMast.

I think that's the best thing... specify where I'm going to use the coax, what I'm using it for (OTA TV), and state that I'd like UV resistance, whether it be black or white.

I saw somewhere a spray called "Stuf" that you spray inside the coax connections before you connect them and it's supposed to help keep out moisture. I know that keeping all the connections moisture-free is very important as well, and had read somewhere about people even using roofing tar for that. That "Stuf" was supposed to also be used with coax seal or cold shrink tape for outer protection. - When I installed the antenna, 18 years back, I had only used regular, black electrical tape under the weather boot on the F-connector on the balun, and on the connections on the grounding block outside.

But do you think switching a 50' outdoor run from Belden Duobond II RG59 to good RG6 will be noticeable in UHF picture quality?

Thanks.
