coax

ionized_gwJuly 5, 2010

I am contemplating installing a rooftop TV antenna. Is there any difference between coaxial cables in terms of UV resistance? I was looking at some coils this morning and there was no mention of this on the packaging.

An "A" in the marking indicates "aerial" use. That would imply ultraviolet resistance.

my friend has coax that he installed on his house 5-6 years ago and its in sunlight for about 8-9 hours during the day and its still performing perfectly and still flexes in the breeze.

P.S. he bought quad shield coax 100 ft at walmart i believe with the connectors on the ends already

sorry but i cant find the link currently if i find it i will post it

I have put up lots of TV coax in the last 30 years. Avoid cable that is any color other than black, and don't buy it at Wal*mart. Get a decent brand like Commscope or Belden, and weather seal the ends properly.

I saw more cable ruined by water ingress than UV deterioration, unless it was jacketed with a color other than black. I can recall only two cases in the last 20 years where I replaced a "black" cable that had significant UV damage. Both were in the late 80's and the cable was 20+ years old.

Thanks, guys. Wayne, how do I weather seal the ends properly?

I like T&B snap-n-seal fittings. (see the link) You can also use a product called "coax seal", or similar Butyl componds sold under other names. If you can get hold of some splicing tape like Scotch 130c, that works very well. Even Super 33+ will work if carefully applied, but it is more difficult to get a lasting seal with 33+.

I took a piece of cable down yesterday that had been spliced with 2 fittings and an F81, then wrapped in 33+ or similar tape. I think it had been up for at least 5 years, the fittings still looked "new" inside.

Here is a link that might be useful: sns
