I have had several homebrew hexbeams, which have survived weather quite well.
1. Use UV-resistant cord, e.g. 3/32" "Antenna Rope" double braided polyester.
2. Paint the fiberglass spreaders, 2 coats, e.g. black "Fusion" spray
paint, recommended for plastic lawn furniture.
3. Use a coaxial center post, i.e. aluminum rod inside aluminum tube,
so that only the stainless steel screw heads are exposed to weather.
4. Use a 90-degree fitting to attach the feedline, so that it can hang
straight down, alongside the center post.
