Is there a man-bucket that will reach 200'? In this area large cranes are
a huge expense, perhaps they're less in Florida. The last time I used a 60
ton 180ft crane (which isn't big enough for Bill's tower) I had to rent it
for eight hours minimum. I had to pay a special road fee for the overweight
crane to drive here. The jib came on a separate truck and had to be
assembled on site. I'm not even sure how the crane will help the severe out
of balance problem. If I were going to go through that expense I would
first build a stronger antenna and switch them.

Bill:
You're gonna have to rent a crane, it looks like. Instead, rent a
man-bucket. Then you and the element ride the thing up to the boom. Then
you come back down alone. Capish?
