(2nd Post - hopefully this time without the html...)
Depending on the climatic conditions (magnitude and rate of temperature
changes) the air dielectric will very likely have condensation form
inside the dielectric and in time have water accumulate at the low point
in the run. The ramification of this is impedance change, increased
vswr, and excessive loss. There are also other dimensional stability and
bending issues with the air dielectric product that may also cause
problems.
All that said, and if I put my amateur radio 'hat' on, I'd say give it a
try since you already have the cable. It does sound like the cable run
will be fairly accessible and could be easily replaced if necessary.
Good luck..
