Parabolic torus reflector antenna

A parabolic torus reflector antenna is a quasi-parabolic antenna, where the defining parabola is not rotated around the main transmission axis, but around an axis which stands vertically to this axis.
Simulsat is a trademark for such antennas designed and manufactured by Antenna Technology Communications.
Whereas parabolic satellite dishes with one low-noise block converter (LNB) are able to receive a satellite television broadcast from one communications satellite at a time, parabolic torus reflector antennas are capable of establishing views to more than 40 C and Ku band satellites simultaneously, by employing multiple LNBs.
