RADIO COVERAGE DIAGRAM

A diagram that shows the area within which a radio station is broadcasting an effective signal strength in relation to a given standard . Note: An example of a radio- coverage diagram is a polar plot, in each direction from the antenna , of the distance from the antenna at which the signal strength is equal to a specified value, i.e., it is the locus of all points at which the signal strength is equal to a specified value.
