Do any of you see a problem in RF tuning or resonance with supporting a

If you keep water off the PVC, all your problems will be mechanical.
A couple of years in the Phoenix sun usually turns PVC into powder.

Hi,

Just prime and paint the pvc pipe with good exterior house latex paint.

Or use sched 80 or 40 PVC electrical grey conduit, no paint needed.
