This whole thing makes me want to climb the mountain and try to put an antenna up there and run old open ladder lead wire down the hill
In all seriousness, I appreciate the ideas, and I will have a LONG chat with the tech at Comcast this week
But back to the antenna-on-the-mountain, it might not be too far-fetched. That's what they did in the 40s and 50s in Bel air, Beverly Hills and Brentwood where there wasn't any TV air signal. A group of homeowners would pool together and have a tower installed, then run 1000' or more of open ladder lead to each house.
In my case though, it's a straight 500' foot granite cliff to the Northeast of us. The nice thing is that the summer sun never hits us! It's in the shade. But in the winter, the sun is up all day
