摘要： A data transmitting/receiving satellite terminal for transmitting to and receiving from a geosynchronous satellite (11) employs an antenna (15A, 15B) having nulls in its antenna receiving pattern at a first frequency corresponding to satellites spaced at regular intervals from the satellite. In addition, a phase and amplitude compensation network (23A, 23B) adjusts a phase and amplitude of the transmitted signal to compensate for transmitting at a different frequency than for which the antenna is optimally designed. The antenna includes a main parabolic reflector, and two side parabolic reflectors offset from a plane parallel to the main parabolic reflector. Each of the reflectors uses a dual frequency feed horn to couple energy to and from the reflector to a dipole exciter to which the receiving electronics are coupled. The above terminal is particularly useful in C-Band applications.

摘要： An adapter (11) for a direct broadcast television system enables owners of existing dish antennas to receive both current analog television broadcasts and new digital broadcasts via C-Band satellites. The adapter includes a coaxial switch (21) for switching between analog and digital television, a tuneable demodulator (23) for selectively switching between transponders on the C-Band satellites, a channel selector unit (25) for selecting the channel specified by the user from the bit stream output by the demodulator, a channel expander (20) for decompressing the video signal, and a control unit (29) for accepting user commands and controlling the polarization of the received signals, the steering of the TVRO antenna (1), the demodulated transponder frequency and the demultiplexed channel. The ability to select the user's channel from multiple channels available on different transponders and different satellites allows the dynamic reassignment of television channels based on system efficiency considerations. The adapter is able to simultaneously serve analog and digital TV to both cable and TVRO and C-Band small antennas and enables a smooth, seamless conversion to digital C-Band receivers with only one box. The adapter may be advantageously used in conjunction with a C-Band or Ku-Band satellite communication system which uses a relatively small receiving antenna while operating within current FCC designated bandwidth and using existing satellite configurations.
