We're between Whitehorse and Haines Junction, Yukon and have satellite TV with a dish about one yard in diameter. It points south and directly at the horizon.
The installer told us the trees might interfere in reception, and the mountains might be a problem, But we've had no issues. Good signal strength.
My understanding is the smaller satellite dishes do not get the best of reception up here.
No cable TV in most of Yukon, Whitehorse has cable though.
No over-the-air TV.
CBC radio changed its service a couple of years ago and now we don't get any radio at our place.
Most RV parks here allow internet usage for basic email and internet browsing. No Netflix, no YouTube, no uploading of big images...the connections are too slow here anyway. It isn't uncommon to be bumped off your connection at an RV park, or to time-out. Video pauses often.
Here at home my ASDL connection frequently times out and has never delivered the speed for which I pay, similar to other users with the same service provider. But we have no choice, there's only one provider here. Unless one opts for satellite internet, which is slower and more expensive.
It is also common for the internet connections to go down in areas, for hours or days. Thus, carry cash with you because grocery stores and gas stations can't process debit or credit cards when the system crashes.
