If you have lived in the mountains for more than 6 hours, you've probably already learned that over the air television reception is nearly non-existent. Not even the biggest 'lightning-rod' of an antenna will help you very much. You are thousands of feet higher than the television broadcast antenna you are trying to receive, so give it up.
In the mountains west of Denver, you COULD sign up for cable service with Rocky Mountain Cable. You could if their rates were competitive with satellite, which they aren't.
I've had great success with Dish Network, and I subscribe to their Family Plan. The family plan is the way to go if you don't need gobs of channels, but whatever package you choose, Dish Network consistently has the best rates.

Note about satellite installation: The installers that satellite companies send up here from the city tend to be very ignorant of the conditions here, and they just want to do the fastest install possible. That is what happened to me. The installer didn't want to take the precautions I mentioned to him, he knew the 'fastest' way to install, so he did it that way, running cables all over the outside of the house (he also drilled through one of my live electrical outlets, in a shower of sparks). By not thinking about the result of these cables everywhere, he installed the cables where ice buildup ripped them apart after only a few months. Since modern satellite systems send voltage through the cable to the dish, it shorted out my satellite receiver and ruined it. I had to replace the receiver and completely re-wire the system myself, running the cables under the house where they should have been in the first place. Don't let this happen to you! Keep after your installer to make sure he is not doing something ignorant.
