I was going to say... in my experience (I've been to a lot of the Arizona electronics sites, having grown up around broadcasting) that most of the microwave equipment in use was for Bell. That was by far the most populous tower on any mountain top. The broadcasters don't send their signals anywhere but either from downtown to the transmiter or in some cases from the big town to a small town to feed a local low power transmitter (like 5kw VHF as opposed to the normal 100kw). Anything else was Satelite. I know the railroad did some wireless (Sprint's towers were also quite densely packed with directional horns) but a lot of their communication for rail signaling was hardwire as far as I was aware.
