I supported myself at university as an engineer at the only TV station
in town. Transmitters [10 KW visual, 5 KW aural] and studio were in a
building at the base of a 400' tower on a ridge overlooking town.
Studio wiring was in trenches in the concrete floor covered with fairly
heavy steel plates. As Mark mentioned, our tower did get hit
occasionally, but it was not a common lightning area. It knocked one or
both transmitters off the air once or twice, sometimes it didn't. Did
not seem to bother the uwave antennas or equipment. What it did do in
the control room, every time, is sound like you were inside a big bell
as all those trench covers rang. [:-)

My experience as a 1st Phone running AM broadcast stations is that the
towers _are_ hit by lightning. This was in the early '70s and all base
insulated towers had a lightening arrestor across the insulator.
Normally the transmitter would drop out momentarily. Most of the
stations had two 833s for the the finals. Guess they can handle some
abuse.
Once I lost a selenium rectifier but that was most likely a power line hit ...
