Dave,
If you are not planning on stacking another antenna on the tower, why not
move the 40M dipole up higher and utilize the additional 7 ft to get the
40M rotatable dipole a bit higher up? That tower seems to have similar
specs to my old US Tower HDX-54 that I have had up close to 20 years. Like
yourself, I have a 20 ft mast and the rotor (Tailtwister) is mounted in the
tower with 3 or so feet of mast in the tower. I use the tower to hold two
Force 12 Magnum antennas. One is a 7 element 12 M beam about 1 ft above
the top of the tower, and the other is an 8 element 10 M beam about 3 ft
from the top of the mast (the U Bolt and saddle that holds the truss cable
for the 10M beam is at the top of the mast). I live on top of a hill, and
have had winds in excess of 70 MPH on more than one occasion.
Have fun erecting the tower. For the first time since I erect it, I had to
do some maintenance last week, and it was sure nice to be able to lower it
down!
