I had my Titan mounted at 12' and at 2'. When at 12' this helped the
receive on 10m and 15m. It also shifted the usable portion of 40 and 80m by
a considerable amount and narrowed that usable portion. As I wanted good
40m performance I tried the low mounting and 40 and 80m improved to specs.
Not that this antenna was a great performer. Sometimes on 40m it worked
super and I can recall many times when I could not make myself be heard. On
80m I did work EU at their sunrise but this thing seemed to be a good dummy
load. It seemed to perform best on 20, 30 & 40m. We are talking bottom of
the sunspot cycle to last spring. The counterpoise has 2 adjustments, one
for 40m and the other for 10m, so I wouldn't remove it as has been suggested
by some. I never did lay down a radial field or ground screen under the
antenna, but not attached to it. I always did wonder if it would help, but
couldn't get any encouragement from anyone that it might. I see from a few
messages that I should have tried it.
