Use an actual street address not a zip code to determine which local channels are closest on sat tv

We live in a rural MT community and they use our zip to decide what our local channels should be. Problem is that it comes up with our county which we are on the outskirts of and the local channel is an hour away from us instead of 1/2 hour like it should be. If they used our street address or took the closest city, we would be great. The local channel they we get shares with another MT city which is 90 miles from the local channel but is actually 140 miles from us!
