For planning the broadcasting-satellite service, it is necessary to make certain assumptions concerning the maximum gain of the antenna (both for transmitting and receiving),and the way in which the gain decreases as a function of the angle measured from the axis of the beam.This information is essential for calculating interference between the transmissions for different service areas.The patterns are given as fiinctions of the relative angle Cplcpo, where cp is the angle measured from the axis of the beam, and cpo is the angular width of the beam measured between the -3 dB levels.The levels are expressed in dB relative to the maximum (on-axis) gain of the antenna.For planning the broadcasting-satellite service,it is necessary to make certain assumptions concerning the maximum gain of the antenna (both for transmitting and receiving), and the way in which the gain decreases as a function of the angle measured from the axis of the beam.
