I know it is the 19th of May and Spring has barely begun, but I just had my Directv Satellite System installed about two weeks ago. My Satellite Dish is about 18 feet in the air on top of the roof, so I do not want to go up there if I do have to to brush off snow. I live in NW Pennsylvania near Lake Erie and we get on Average between 8-10 feet of snow during the winter months. 1) can you recommend a good manufacturer. 2) can you reccomend a good supplier 3) is it a self install, or should a professional do it I have a Slimline-35 (SWM) Satellite Dish Thank You for your help..
