I forget the exact frequency, somewhere in the 2GHz range. Xicom makes
the amplifiers.

I'll accept something like that. What frequency range does the
terrestrial signal occupy?

I would have figured something smaller and several of them in a city,
not just one multi-kilowatt transmitter.

In My area we have cell phone extenders that look about like this.
XM terrestrial repeaters are usually on large buildings or hills and
they use a several KW Klystron amplifier, which takes a 6ft rack for
the redundant pair. Don't think that is stuffed inside the lamp pole....
