I had good luck with Schedule 40 and a broomstick, as well. Run the broomstick through the PVC and bolt it twice on each end such that each end has two bolts running through it in a 'cross' configuration.
It's not as light as fiberglass but the rigidity is great for my 2x8element array 25 feet off the ground.

Pretty simple to make a fiber pole functional equal.
use a pc of schedule 40 PVC pipe. apply a couple of wraps of 5 oz glass cloth using epoxy or polyester resin. The glass will prevent the PVC from sagging and adds great strength.

Hi Bob,
I ordered the fiberglass M2 boom from RANDL.com, item HDFGBOOMKIT (http://www.rlham.com/cgi-bin/shop/modellookup.dbw?MODEL=HDFGBOOMKIT); however, is a bit pricey at $184.95 plus shipping. I have read where
other
homemade methods have been used with success.
Are you going to use both azimuth and elevation rotors or just azimuth?

In putting together my antenna,?? (144-432)I need something to use as a horizontal- cross? support boom. What would be the best length, and,?
what
would be the minimum length,,,? would 6? ft separation be OK?? To
minimize
problems, should I mount one beam horizontal, one vertical? Does it
matter
which one, is? which way?
I doubt I can find a fiberglas boom locally,,,? what else could I use?? or, where can I order a fiberglas boom?
