Bob-
These comments only address the issue of easy erection of the vertical
on the tripod ...
I would suggest you mount a short mast in the 3-foot tripod. The short
mast to have two 1/4" or 3/8" holes drilled in it about 3-feet apart.
Mount the antenna on another short mast ... this mast to have another
pair of matching holes.
Given this arrangement, put a bolt through the "upper" holes in the mast
pair. Then, the only problem is to swing the antenna into a vertical
position ... if push comes to shove insert a length of pipe in the lower
mast to give you more leverage. When the antenna is vertical, slip in
the second bolt.
I used this to install an R7 on a 22-foot mast on my RV. It worked like
a charm ... and it sure beats running around the roof trying to balance
a 25 (or so) foot vertical. :-)
