a satellite system for transmission of signals of two different frequencies and polarizations simultaneously , and will accommodate two different polarity commands from different sources at the same time . the satellite system includes a satellite antenna that receives signals . a head - in frequency processor enables the different frequencies and polarizations to be transmitted simultaneously via a single coaxial cable . this single coaxial cable is coupled to a head - out receiver processor which is connected to a receiver . this configuration provides for the system that will permit for satellite broadcasting in locations that are not in the line - of - sight path to the satellites such as high - rises , hospitals , condominiums , schools , and the like .
