The best way for install a Ka-Ku, or Slimline dish is in a pole, Why ? because the size of the dish, if you want to install the dish in the roof, ..., is 6 holes for the foot, 4 extra holes for the braces, total 10 holes, the technician can use bishop tape, silicon, etc, but the 10 holes are in the Customer roof, probably out of the living area, probably whit insulation, ... and... y two, three, or five years, you can ask Why I no use a pole ?
A friend recently had a pole mount near the house, no charge. However, as stated above/below...there was a line-of-sight issue with the house and eaves. I noted that the pole mount is sans support arms. Dish has been ok though, no movement.
