I'm having my DirecTV service installed tomorrow. I'll be getting the Slimline dish as I've ordered one of the HD packages. I have an installation question... My preference is to have the dish installed in my townhome's backyard as my HOA prefers that we install dishes where they won't be visible from the street. But it's obvious the HOA can't force the homeowners not to install dishes on roofs as I've seen a few D* dishes in my neighborhood mounted on roofs and under eaves. My roof is tiled and sloped, but an under eave mount should work and have a LOS. I'll play nice though with the HOA and have the dish installed in my yard if possible. I've already determined a dish mounted near the rear cinder block wall in my yard would have a LOS with the 99, 101 and 103 satellites. My question is, does the dish HAVE to be pole-mounted or can it be mounted on the block wall? I'm wondering if the weight would be too much? A pole install would cost me extra and require a 2nd trip to allow the cement to set before the dish can be installed. I'd like to have the dish install completed tomorrow so I don't have to ask for time off work next week. The height of the wall is 4'6".
