Dave-
See you have two replies, one yes and one no. I had the same concern
when I put up an 11-el 2M beam about 10 years ago so I used PVC for a
mast section. I selected a size PVC that would just slide over the
steel mast, cut a 4-foot length, cut a slit about 4" long on either side
of the PVC and used a hose clamp to fasten it to the steel mast. Has
worked fine.
