Abstract

A satellite signal distribution system distributes signal blocks of two different received frequencies and polarities simultaneously over the same cable. The satellite system includes a satellite dish or antenna that receives signals. These received signals are transmitted to a block frequency converter that enables the different frequency polarity blocks to be distributed simultaneously via a single cable. The cable is coupled to a head-out receiver processor which distributes the signals to satellite receivers. The receivers are connected to TVs or other sources. This unique design and configuration provides for a system that will permit satellite broadcast signal distribution to high-rise buildings, hospitals, condominiums, schools, and the like.

Claims

1. A satellite broadcasting system comprising:

a satellite dish antenna receiving vertical and horizontal polarization signal blocks from at least one satellite;

a block frequency converter coupled to receive the received signal blocks, the block frequency converter frequency-converting the vertical polarization and horizontal polarization signal blocks received from said satellite to different frequency blocks; and

an amplifier arrangement coupled to said block frequency converter, said amplifier arrangement amplifying said converted signal blocks and applying said signal blocks simultaneously to a single coaxial cable for enabling said two different blocks to be distributed simultaneously via said single coaxial cable.

2. A satellite broadcasting system as in claim 1 further comprising a satellite receiver coupled to the cable.

3. A satellite broadcasting system as in claim 2 further including a power source coupled to said block frequency converter.

4. A satellite broadcasting system as in claim 2 wherein said block frequency converter provides for said signals to be converted separately and independently by said satellite receiver.

5. A satellite broadcasting system as in claim 2 wherein said block frequency converter allows said signals to be selectively converted to said satellite receiver.

6. A satellite broadcasting system as in claim 5 further including a switch for selecting between said blocks to be selectively converted by said satellite receiver.
