I'd agree. I've made and used fiberglass covered Bamboo Quad spreaders. They
worked well and lasted for many years. But they were hard to make, they were
very heavy, and fiberglass resin is nasty stuff to work with. Modern fiberglass
spreaders like those available from Cubex of Max Gain Systems are much better.

Subject: Re: [CQ-Contest] Quad Antennas performance for Contesting
Renner, in an older book of W6SAI "All about cubical quad antennas" he writes
about "waterpoof your bamboo arms with fibreglass". Basically he suggests to
cover the arms with fibreglass, which is typically used for car- or boat
repairs. However I would probably directly replace the arms with fibre and not
try the bamboo at all. Unless you plan some "portable style" contesting I
believe the slightly higher cost will pay out. Vy 73 Uwe, DL8OBF >
