Speaking for some personal experiments several years ago, you should see at
least a 10 dB increase in signal levels, depending on the frequency, your
roof materials and the height increase over the old attic antennas. You
could always tell them it's only a TV antenna(s).
Good Luck,
George

Subject: [VHFcontesting] Log Periodic Antenna Performance?
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?
