I am having an installer come to mount a Direct TV Ka/Ku Dish. I don't want him to mount it on my house roof (because it is shed style) and therefore am wanting to build a bracket that would substitute for a fascia board. I am looking for a PDF of the Direct TV satellite dish installer's guide. It is a 2" OD mount and I believe the footprint for the base 4 screws is 5" horizontal spacing and 7 7/8* vertical spacing. Thanks.
