I currently have dish network and am considering switching to dtv. my dish is installed near the center of the roof the wires lead from there into the attic. if i go with dtv, i would like their dish to be located very near my existing dish. searching around some say installers are no longer allowed to leave their ladder for roof installs. if so, they could not install the dtv dish where i would like it to be located. i further understand that this is due to a osha regulation that came out a few years ago. apparently, it applies if a company has 50 or more employees. i am not sure if dtv installers are dtv employees are contracted out positions. so what is the real story here? i have a 2 story house and the current dish is located "2nd story roof". i know it is difficult to visualize, but if you were to fall from this 2nd story location, you would actually fall just 3 feet onto the 1st story roof which is level at that location. so it is a nice hidden location with perfect line of site.
