Hi Sig,

Since a coil loaded elevated radial system is pretty inefficient 
anyway, I don't think the loss of Q caused by using PVC would 
hurt much anyway.

If the system had reasonably high efficiency, then the PVC would 
be a problem.

I would worry about moisture detuning the coils. Put them in some 
kind of enclosure that keeps water away from the coil.
