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. Som

I'd suspect that the 45 foot height advantage plus having the antennas out in the open is going to make up for any gain losses due to it being an LPA. 73, Zack W9SZ __________________________________

There are a number of "reasonable accommodation" laws which probably what was used here. I'm not sure if 45' falls under "reasonable accommodation" but its sure worth a shot. There is also the unwrit

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 w

Hi everyone, I'm new to the group, but I thought I would weigh in.   I would think simply putting up the same type of antenna as your neighbor did would yield better results on 6 and 2 than the indoo

Les, I'm not an attorney, but I would guess that most probably your neighbor was able to erect the outdoor TV antenna because it was a RECEIVE ONLY antenna. I believe the same federal law allows the

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 o

I agree, George and Sebastian are right on, just tell them it is a TV antenna.    The roof material is definately a huge loss especially at the highter frequencies.   Even an unmodified TV LPDA will

Les: Depending on the construction of your home, you may or may not see too much of a difference. The exterior LPA will have substantially less gain than the single band antennas, but if your roof ha
