It took a while to find the excellent write-up on W3GM
in NCI May 1991 but here is a statement in the write-up:
"All of his towers, which include several 100-footers,
fold over at the base with hinge and gin-pole assemblies.
A hand-drill-driven boat winch easily brings his big
antennas down to a height where he can work on them alone."
NCI, May 1991 quote.
I called Gerry on the phone in 91 as I was interested
in the 40 meter beam on 100 foot tower. Gerry (with health problems then)
said it was 25G and he lifted it all - tower, beam, guys & rotator at once.
Special
high gin pole for lift cable and I seem to recall he said the support cable
connected
in more than one location and guys were in place with 2 sets? connected
to ground supports on starting the lift.
Can anyone that helped or saw the operation of these base hinged towers
tell us more??
