(perhaps off topic, but) Microwave Towers

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.
