To add to the latter part of your question...we have our dish set up on a tripod. Our dealer told us thats the only one that will work in the US using your Canadian service. Last year talked to a neighbor RV`er who had his dish roof mounted and he said often times once he is in a site, there are too many trees in the way for him to catch a signal...at least with a tripod mount you can usually set up in a clearing...just make sure you have plenty of cable.
