Scrambled satellite cable programming is received at a central
location where it is processed and fed into special transmitters.
The SHF transmitters distribute the programming throughout the
coverage area. The signals are received by special antennas
installed on subscribers' roofs, combined with the existing VHF
and UHF channels from the subscriber's existing antenna, and
distributed within the home or building through coaxial cable into
a channel program selector located near the television set.
Notice that you must provide a UHF and/or VHF antenna if you want
the broadcast channels. This is because the Wireless Cable Box
only provides a UHF/VHF tuner. Of course, not all boxes include
even this feature (but most do).
