Powerlines are 60 Hz. He said anything under 200 MHz is OK, so that
should be a non-issue. (Assuming there isn't any
broadband-over-powerline system in his area, at least.)
I thought that it was a higher frequency (as well as voltage) up to
the transformer. Maybe I'm wrong...
I can't say you're wrong, but I can say that changing voltage is easy,
requiring a simple transformer; changing frequency is a bit harder and
would require some additional circuitry; I can't see the power companies
bothering to change the frequency; I see no advantage to it.
