WA9TVH (A step ahead of TVI) since 1965. Also DA1QD.
As to the HF antenna supports, I'll see if I have some pictures of my system. It uses a couple of 16' long fishing poles (Fiberglass of course) and some WW-II era lightweight phosphor bronze antenna wire. The vertical support is thick wall aluminum tubing formerly serving as side poles for military stretchers.
The dream antenna support would be a 36' pneumatic mast mounted to the back bumper of the EggCamper
. Still trying to sell the XYL on that one though.
