I'm looking to have a DirecTV dish installed on my multi-unit condo building in Metro Detroit and was wondering if anyone could recommend an installer. The building has a central backbone for wiring and already has a Dish Network dish on the roof wired through the central core, which provides easy access to every unit who wants to activate it. If you could recommend anyone who has experience with this and is reputable in the metro Detroit area in terms of servicing the dish if problems arise, please let me know. THANKS!
