Choosing A Mobile Radio Scanner
Some people get a mobile radio scanner because they enjoy following police and emergency vehicle responses or are assisting policy in some way in a volunteer capacity. Other people need the scanner because they live in an area that has such severe weather that they can be left in perilous situations if they are not aware of incoming storms or must be able to get help when there is not electricity.
Mobile radio scanners are available in many styles and designs that fit the individual needs of their users. Some scanners are manufactured with the built-in capability to send an emergency signal to police and emergency services departments. Other scanners are designed to be used both in a vehicle or as a base station in a home.
Most of the mobile scanners can pick up frequencies as much as forty miles from a person’s location depending on the type of antenna that they use with their system. The magnetic antenna is the most common choice for many people who use their mobile radio scanner frequently. This antenna uses a vehicle as a part of the receiving unit and has a clearer output than other antennas. It can also be used to add range to a base station 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.
The scanners store thousands of channels and can scan hundreds of frequencies per second. Some of the scanners can follow trunked systems and the APCO-Project 25 digital radio frequencies used by federal, state, and local public agencies. Since the increase in terrorism and need for more secure communication, a mobile radio scanner cannot receive encrypted transmissions legally.
Having a mobile radio scanner is a great asset when one is traveling. It is very easy to receive weather and traffic information as well as police bands for the area in which one is traveling. By using the scanner one can effectively avoid any accidents that may be on the road ahead or inclimate weather that may require adjusting the route that is being traveled.
