The digital trunking scanner catches data through VHF, UHF and other types of frequency to transmit data.

Police scanners are the other known name given to scanners. Back in the days, scanners were commonly used by policemen to inform their fellow policemen that a crime has just happened. This is an easier to easily respond to a current situation. Firemen also use the same scanner to alert their department about a fire. The good thing about scanners is that it receives data from the nearest active channel. If a certain policeman reports about a crime, the nearest policemen would immediately catch this active frequency and be informed about a current situation.

The main parts of a scanner are the antenna, battery, case for the scanner and a software if the scanner manufacturer provides it.

What are the role of these parts in a trunking scanner? The antennas main role is of course to improve the signal that the scanner receives. The longer your antenna is, the better is the signal.

But enjoy more about the scanners’ functionality or give you more options on channels, it is better if you would learn how to program. Some digital trunking scanners do come with software that has a user-friendly interface that would allow users to automatically add a certain channel. Although most of these software have compatibility issues with some computers or devices.
