Enter the diameter of your parabolic dish in m (metres) and the operating frequency in GHz (Gigahertz) A typical VSAT is 1.2m diameter. The driven element can be a dipole antenna or a horn antenna. FM radio stations run circular polarization.Ī dish antenna consists of an active, or driven, element and a passive parabolic orspherical reflector.

Chapter 4 PARABOLIC DISH ANTENNAS Paul Wade N1BWT © 1994,1998 Introduction Parabolic dish antennas can provide extremely high gains at microwave frequencies.Īntenna, VE3.The high level of gain that can be achieved by using a parabolic reflector is. Parabolic reflector antenna gain is one of the key parameters of this type of antenna.
