Anyone have experience of making VHF antennas with non conducting booms?

The one I made for 200 MHz (TV channel 11) was made from a couple of
pieces of 3/4"-square clear fir, with copper-plated-steel welding rod
segments for elements. Worked fine.

I think I ought to be able to employ a non conducting boom for a yagi design
that is no more than about 50" (1.27 meters) in length. Must have sufficient
rigidity.

I was thinking about using a square boom made out of some synthetic material
(NOT wood). Obviously tthe material must not degrade over time in an
outdoor environment.

I've seen square, hollow rods made of fiberglass. Should work
reasonably well as long as you drill it carefully, cap the ends to
keep and wind out, and paint it afterwards to protect the resin from
solar UV.
