Shaw Direct is a good choice. I have heard stories, true or not, that indicated that once out of Canada, Bell customers have more trouble with their provider. Not sure about compatiblity with what you now have on your roof, but there are automatic systems for the Shaw Direct service. Budget minded RVers often use tripod mounted dishes, or other contraptions for the dish, to gather the signals. These can help defeat potential signal-blocking overhead obstacles where the vehicle itself is in a fixed position. The larger Shaw dishes give service to a broader North American area than any provider, Canada through to Central America. Like Bell they also give you Hockey, but maybe not this year.
