I am getting a bit frustrated w/ OTA reception. I live in a typical Phila Rowhome. Those of you around the country w/ know it as a Townhome. They are a row of brick homes built in the 20's. I have been trying to get OTA HD in phila w/ an indoor antenna. I have a Dish 811 reciever. I have both the Radio shack indoor HD antenna. And the RCA VHF/UHF indoor Ant. With a VHF Uhf Preamp. I can pickup nothing w/ the Rad Shack ant. The RCA gets me NBC, CBS and UPN digital but these cut out frequently as well. I'm about to try a SqS ant but i cant put it on the roof. Does anyone have any expeirence w/ this ant. Do you think it w/ help? Seeing as how i'm only 15 miles from the broadcast towers w/ no big buildings in the way. I thought this would be a piece o' cake.
