You're correct, for most amateur applications steel is probably the way
to go..... but these are light enough to yank up and down, and if you were
inclined to fool around with wire antennas it would make the model
simpler... they might be perfect for field day.... They claim these
structures are useful as replacements for utility poles, if they're very
"leaky" an insulator failure could be very exciting... in any case, it might
be fun to look at a few.... I wonder if I need my passport to go to Utah....
don't they have a bounty on Catholics?
If somebody spots one in Oregon or Washington, I'd like to hear about
it... maybe save a few miles
