Afternoon everyone,

I'm rebuilding my Bugcatcher antenna. It works well, but the XYL had a
bit of an accident last year when we had a big snowstorm, the leaves
weighted down the limbs, and the antenna, which was strapped down, still
managed to introduce itself to a limb.

Anyhow, the original antenna was mounted using 1 inch thick plexiglass,
with holes drilled to run the mast through, and tapped screw holes to
mount to the back up plate, in turn mounted to the spare tire holder.

I'm trying to make something a little prettier now that I'm rebuilding it.

But the thing is, I'm curious about the material. Is there any
particular material to avoid? I know Plexi works, but what about PVC?
Delrin? Bondo? 8^) Miiling, water absorption, etc?

I have grown fond of nylon/teflon material, problem is, these materials
are difficult to find locally, and are expensive when found. In a
pinch, those plastic kitchen cutting boards are pressed into service
here. The are an opaque material, kind of "translucent white", softer
than plexiglass but hold up well under stress, will bend or warp rather
than break, seem to resist UV well enough, seem to exhibit good
insulation qualities up to VHF at least (highest freqs I have used them
at.) They can be cheaply had at used stores. They are usually 1/2
thick. Perhaps two sheets bonded or fastened together with brass/SS
hardware?
