Thinking of putting a vertical up. I'd go from 2" pvc, to 1", to 1/2" ,
in twenty foot lengths. Will this thing support itself OK? Seems like it
might physically work OK.

Been there tried that-
It won't work.
I tried sched 40 plumbing PVC and the gray PVC sched 40 (electrical).
Pvc is ok for a 2-meter quad - but use alum or steel mast,
you may try the top-post they use for chain-link fences - I think you can
get it in 20-ft lengths.
