I do not know how well these work, but I have been thinking about one for our
restricted mountain cabin. I think it will work well at 2500 ft in the
mountains, at least better than the loops and wires I have hidden in the woods
now. The 50 to 500mhz one is the one I may use.

A few days ago I noticed that one of my neighbors in our deed restricted
neighborhood had erected an outdoor TV antenna, complete with a rotor and
heavy duty mast to raise it above the roof line. Some polite inquires revealed
that our home owners association had been forced to allow the antenna under
Federal Law.
More checking, and study makes it seem like this might really be an option for
myself as well. Most of you know that I've been chasing VUCC on 6-1.2ghz
for
the past year or so using nothing but an attic full of indoor antennas.
I'm now in the process of drafting a proposal to allow the erection of a 45
foot tower my back yard, with a single log periodic antenna and rotor. The
hardline feedline would be connected to an "A/B" switch to allow the
signals
to be routed to either my television set or the ham shack.
My basic question is what can of improvement am I likely to see over the
single band beams in the attic vs. a LPA? Which model would offer the best
performance? Is it going to be worth the trouble, expense, and possible legal
fees necessary?
