my experience only.
I have used PVC and it looks good for a while. The sun tends to warm it up and it begins to show warping. After while it looks crappy. Like a not so stiff worm .
Sure PVC is cheap and it does tend to make cheap temp antennas that usually have a short life span.
Most importantly is that "you gotta do what you gotta do." to get on the air.
As for the mentioned Fiberglas poles from EBAY. I bought 3 of them. They do not telescope but are Ex Military and in the green carry bag with all the military markings. Buy it now $7.50 and $24.00 for shipping NY to KS USPS.
12 poles @ 48" long I thought it was a decent deal.
Field day, vert antenna, support for long wire, many potential uses.
let us know what you do and how it worked out for ya.
