Do NOT go with A1... The installer came out on the wrong day, and before I could get home and tell him to cease and desist, he demolished my DirectTV setup, disconnected my cable modem taking down 3 VoIP phone lines as well as my Internet email and web servers, and only then started putting up the new equipment (Dish 500) before verifying LOS to E* satellites! (I did not have LOS to E* at the DirectTV mast location.) I had two other technicians from A1 come out and try to rectify matters, but frankly they were all marginally competent. Even simple things like screwing down the mast roof bracket were done (1) with very small diameter screws placed (2) through holes nearest to the mast, rather than the farthest out for best leverage. Of course that antenna blew down during our first strong wind, and it's only by God's grace that it snagged on my gutter rather than crashing through our kitchen window.
