I live in Northwest Florida and am getting ready to add locals (notHD). They are on 129. I already have a dISH 500 and a single dish on 61.5. I hear a lot of people complaining about 129, where my locals are (Mobile, Ala). Should I have the installer install a single dish for 110,119, and 129. or keep the setup that I now have and have him just point the 61.5 dish at 129. Would this get me a stronger 129 signal, than a single dish solution. I am switching to the DVR advantage package , so the installation is susposed to be free.
