Hey Stewart!
 
So those frequencies are more penetrating to the walls of anything and must be everywhere as well. Loni

Hi Loni,

> Thanks for your response Stewart! So are there antennas at police and fire stations putting out this frequency 450 MHz? Loni

Back in the late 1990's I got a scanner to keep from being bored, and I
got a book /Radio/ /Call/ from Radio Shack that lists every public and
corporate radio registered with the FCC, plus walkie-talkie frequencies,
pagers, trains, you name it. It's a thick book. Then there are ham
operators and shortwave radio. The world is really awash in RF EMR as
compared to over a century ago.

One of the 11 bands the scanner covers is a public band between 450Mhz
and 470 MHz.
Usually the transmitting antenna is up high, on one or more towers on
the highest hills of the county.
