We, too, have the KVH A7 unit, because, well, I'm lazy and didn't want have to drag a dish out and try to set it up. Did that two or three times and said, "UM, no, not gonna do THIS anymore. . will read instead!" ha ha
We went with the A7 so that it would sit nice and low on the roof, allowing us to still fit through the garage door, and really, I think it looks better too. We pay an extra $5 a month to DirecTV for that service in our bus. . . can't beat that.
