Many will advise AGAINST the use of coax with a mostly air dielectric for an
exterior installation (most) because of moisture condensation inside of the
coax air space, i.e.. 9913. Better velocity factor, yes, less loss, yes,
until it gets moisture inside, then it's ruined, or will be in a few weeks
when it all corrodes. 9914? I haven't used this and don't know the
dielectric, if the same, same scenario. Just repeating others opinions that
seemed to make sense. HF? Mil spec RG213 works fine, what I use is direct
bury and UV resistant. UHF, maybe the velocity factor and loss difference
is worth replaceing it more often.
