We have an Intellian I6. The farthest north we have been with the boat is Juneau, and it works that far, sort of. We have Dish network for the US, but Dish is US only and quits shortly after we cross the southern border of Canada on the way north. Canadian Bell works in Canada but requires a different (Bell) receiver and activating that account.
Then it quits when we cross the border into Alaska and we have to go back to the Dish receiver and account. On either system and at any given time, we can never be sure what channels will work and which won’t. The whole setup might be more trouble than its worth for us. Seems like it always need some time and effort to get it to work and its usually not enough of a priority for us to bother.
