I have DirecTV, which I am NOT considering cancelling at this time, but I'm thinking about having an antenna installed on my roof to use in the event of station blackouts due to fee fights. It would also be nice to have on rare occasions when snow blocks out my satellite reception, which on occasion has knocked out our satellite reception for more than 24 hours. I'm trying to determine if I can get the local network affiliates where I live, which is in the 30189 area code northwest of Atlanta, across town from where most of the stations are located. Antennaweb shows channel 57, a non-network station, as the only station accessible from here, but the FCC site DTV Reception Maps shows channels 5, 11, 46, and 69 as "strong" from this zip code and channel 2 as "moderate". Does anyone know why these sites show different results and which is accurate?
