Well, the frost out here took its toll. Need to re-plumb and relocate a

lots of CAT-5 sitting on two spools doing nothing. I know, I know, it's
not what you are 'sposed to use outdoors but it'll save me a drive into
town.

What happens to CAT-5 outdoors when part of it is buried in the soil and
another part is exposed to the sun? Regular stuff, not plenum rated.
It's going to get 24V, not much current, probably 250mA or so and I can
parallel all the pairs. Any experience?

BTW, I have in the past used indoor telephone line outdoors and it
lasted forever. But that was much older technology, four non-twisted
wires in a gray jacket. Then I had non-stranded electricians wire as an
antenna, high up there, looked like new after 15+ years. Amazing.


For a "temporary" outdoor suspended run of CAT-5 which has lasted 5
years, I painted the jacket with white primer paint. This is located
in Central Calif. Stuff I inspected after 2 years was still in good
condition. Maybe primer paint, then a coating of latex.

Yep. Latex will even protect exposed PVC pipe from the Arizona sun.

Hey, Mark! Doing anything interesting yet?
