This question already has an answer here:
I have a winegard 8200 series antenna and it worked flawlessly in getting me reception of more than 70 stations. The wind blew it down and I couldn't replace it for about 6 months due to the fact that I couldn't get a suitable man lift into my yard because of the season and ground conditions. When I replaced it with a new one, my reception was seriously limited. I could receive signals in both the UHF and VHF ranges, however only a few in each. I have a rotor and tried every adjustment. I replaced the coaxial cable, my amplifier and the splitter card from winegard. Nothing worked. I was about to give up, when, out of the blue, my reception became flawless again! It only lasted a week and reverted to the limited reception that was unsatisfactory. I have discussed the issue with Winegard and they suggest that it is not an antenna issue. My neighbor is a Ham radio operator and his house is located between me and the broadcasting stations in the large metro area to the East of me approximately 60 miles away. I just learned that he is an amateur radio guy, because he has no large antenna on his property, which I thought was requisite for a Ham operator. My question is, can his equipment be somehow blocking my reception?
