Selecting a mobile radio scanner will greatly depend on the purpose that it is being purchased for. If an individual wishes to monitor transmissions within a local area, they will find that a lower end scanner will be effective. However, if the scanner will be used in an area where a person may require emergency assistance there are scanners made that have emergency beacons built into them.

The many options and features available on mobile radio scanners make them a tool that can fit the needs of any individual. The scanners are manufactured for use within a vehicle or in other locations. Many people find that having a mobile radio scanner allows them to move the scanner to their home base unit easily.

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. A magnetic antenna which uses the vehicle as the ground for the antenna often has a greater receiving capacity and clearer audio than other antennas. In addition, this antenna can easily be transferred to a home base unit to increase the capacity of a home antenna.

The magnetic mounted antenna can move removed from a vehicle easily and used to increase the range of a base unit’s antenna. A person will find that since these antennas use the vehicle as the ground for the antenna it gets a longer range as well as clearer audio quality from the scanner.

Depending on the scanner selected, a mobile radio scanner is capable of monitoring hundreds of channels between 30Mhz and 3Ghz. 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.

An individual can store thousands of channels on their scanner. It is possible to scan hundreds of frequencies per second. There are scanners manufactured that also can follow APCO-PC 25 digital frequencies and trunked systems. These frequencies are used by emergency services and security agencies in the federal, state, and local governments. Some of the transmissions of these agencies is encrypted and mobile radio scanners cannot receive them for security purposes.

There are many times when the mobile radio scanner that one selects will provide security. This is especially true of individuals who travel a lot or live in areas with severe climate changes. Having a mobile scanner that can receive important information when one is traveling, or emit an emergency beacon when a person is stranded is of enormous benefit to most people.
