Shaw Direct works well all the way into Mexico with the 75cm dish EXCEPT for the HD channels. As I type this we in Puerto Vallarta watching the Bronze Medal game of the Briar Curling on TSN.
DO NOT tell Shaw that you are taking it to the USA. Get is set up in the stick house and simply move a receiver to the rig.
They do now have an RV arrangement to get the extra dish and LNB needed but it will cost. We got ours many years ago when Starchoice would supply it free--including shipping!
An automatic dish will set you back several thousand but really takes the frustration out of it, especially for one night stays. Or catching the Noon News at a lunch stop!
We could not find an installer but there is one in Langley who comes over to the Island occasionally or you can go to him. PM me for his phone number. I have it somewhere but will have to dig it out
We have used the Starchoice (now Shaw Direct)system at home for decades, before cable came into the neighbourhood. We found it to be as good as cable and now can just swap receivers whenever we wish.
We have
this one.
