Does anyone know if I can get local HDTV stations via DirecTV sat in Madison, WI with a south-pointing dish? Just curious because it wasn't possible on Dish Network. The dish would've had to point to the east, which doesn't work for me due to a large hill with large trees on that end of my yard. 3 years ago when I last had DTV, I was able to get locals in HD via a south-pointing dish. Is this still the case? Thanks!
