Bob, I would keep the screwdriver on your car or truck. At the very
best, it will be an inefficient radiator on 160-30, regardless of where
you put it on your tower. Instead, I suggest you try shunt feeding and
omega matching the tower itself. Your 12 radials are a good start, and
the tower, with the yagi as a top load, should give you an effective
length somewhere between quarter waves on 80 and 160 meters.
