Query: not good reception for downtown in the mountains.

Big let down. So many outstanding reviews I was excited to see what this jewel could do. No better than my old antenna that was designed for analog reception, with enough UHF for receiving PBS. I turned it 360 degrees and found the best direction couldn't even get CBS, let alone... To be fair, I do live in the mountains. Still, this fish cannot fly.
