Satellite antennas are used in various fields that need data from and passed through satellites. There is an ever increasing need for communications with satellites, including reception of satellite broadcasts such as television and data and transmission to satellites in vehicles. The use of satellite antennas for reception of television transmissions from satellites has increased rapidly in recent years. The use of satellite antenna allows households to have access to much more television channels than the number of channels that are available through local cable television systems. Satellite antennas have also allowed television transmissions to be accessible to rural households which may not have access to cable television. In recent years, satellite communications have been finding widespread use as a new data transmission medium in international and domestic communication fields. A satellite communication system comprises a satellite orbiting around the earth and transmission and reception earth stations for accessing the satellite. Satellite communication systems typically beam signals from a terrestrial antenna to a geostationary satellite. A typical satellite receive antenna uses a parabolic reflector dish to reflect and concentrate signals to a focal point. A feedhorn or waveguide is positioned at the focal point to receive the focused signals. The feedhorn directs the concentrated signals to a probe which responds to the focused signals by producing a small electrical signal.
