I got my 1/25" diameter solid fiberglass boom from www.MGS4U.com at what I think was a reasonable price. I painted it white to protect the finish and it's working quite well. I have three sat antennas on it: 70cm and 23cm on one side of the rotor and a 2m on the opposite side. To aid in clamping the antennas and the EL rotor to the boom, I cut appropriately-sized sections of PVC pipe to place at those clamping points. I then applied self-adhesive non-skid tread to the boom, attached the PVC sections over the non-skid tread, slid the fiberglass boom into the EL rotor, and attached the antennas. Seems to be working just fine.

All:
Is there a cheaper non-metallic alternative to fiberglass cross booms? Or maybe a wholesale fiberglass rod distributor that has such a beast at a reasonable price?
