Don't know how you can do antenna work from inside the tower, but guess you
have that covered...
Since I've had mine up for 5 years, I'm going on memory, but have been very
pleased with the performance. Obviously, you would have to be able to reach
the center of the driven elements to make the switch between one and three
feedlines. I would assume that individual baluns would be needed on each
feedline, but these can be just coiled coax. Force 12 supplies all materials
for
either feed method so you can make the choice when you put it up. Since I
fed mine with a single line, I have an extra coil left over. With multiple
coax feeds, you should have a few shorting bars left over. With single
feed,
I do have a bit higher SWR on 15 as has been noted previously on the
reflector.
