What are Repeated
Frequencies?
Imagine that you are a police officer. You are stationed in
an area that is over 40 miles away from your main
headquarters. Yet, when you radio your headquarters, you can
hear them loud and clear. How is this possible?
Repeaters are devices that broadcast activity
on a frequency in order to extend the range of a
transmission. For an example of this, reference the picture
below.
The above picture is an excellent representation of how repeaters
work. They are vital to the success of any type of mobile
agency, as they allow the mobile unit to communicate to the base
station with ease. Moreover, they are the basis by which
trunked radio systems and encrypted radio systems are founded
upon.
