We are north of Tampa and all of the signals come generally
from
that direction.
Arm-strong rotation of the beam requires only a tiny
movement to
bring one group of stations in strong and lose several
others or to
have the majority of them and a few lost but several at the
compromise
position are erratic.

I operate 6, 2, and 440. The closest of those antennas is
about 30 feet off the
back-side corner of the TV beam.
I currently run less than 100W on 6M and less than that on 2
& 440.
The 6M antennas are a Delta loop and a horizontally
polarized beam -
the beam is not yet up but will probably be fixed
west-northwest - so
back-to-back to the TV beam (and 30 feet away).
I also sometimes use a dipole via a tuner that is further
away and my 6BTV
HF vertical which is ground mounted about 20 feet away from
the push-up
pole that supports the TV beam.

Someone recommended a Winegard and I am looking at those -
bonus
that is it USA-made!

The TV beam is a multi-element on VHF and on UHF, it is
intended
for fringe use. I don't know the brand as I received it used.
We have a lot of UHF TV stations here in the Tampa area.

That was helpful info, thanks!
