I have a Rohn 65 design in CAD, never built it, went with rings instead.
Should have done the arms. All 1/4" HRS steel plate, standard angles
and channel, plus 2" NPT pipe, although other tube/pipe choices are
easy. Different leg diameters depend on the u-bolt size (minor hole
location change needed). Designed for hot dip galvanizing. I designed
for two antennas for up to 20' of pipe between top bearing and rotator.
Or one antenna on a short pivot "mast". Uses a standard mount rotator at
the bottom (my plan was Orion 2800) and a UHMW bearing at the top. Make
the plates on a laser or waterjet cutter. Weld it up and HDG.
Reply off list and I well send 3D pdf's to review. Enough interest and
some weld shop might make them. Everything should UPS except the pipe,
buy it locally. Adding tabs and slots to the top and bottom supports
for self fixturing of the welding would be nice.
