On average a mobile scanner will pick up a frequency up to 40 miles from the location of the scanner. This depends on the type of antenna and location of the individual.

VHF monitoring falls within 30Mhz and 300Mhz, This frequency is used primarily by the military, police, air traffic controllers, etc. The VHF to UHF is between 300Mhz and 3Ghz and is used by public service agencies with their two-way radios.
