A TV antenna and/or DSS antenna and provision for DSS distribution throughout the home from the Communication closet is not just an alternative to CATV. The planning and installation should include provisions for DSS even though CATV is available. Many homeowners want either an alternative to CATV, or both CATV and DSS services. HDTV reception may also need to be considered. The DSS antenna may require one, two, or four RG-6 quad shielded cables to the Structured wiring panel, and from there to DSS receiver locations. Most RG-6 quad shield cables for video and TV distribution within the home use a copper clad steel core to provide optimum video signal performance and cable strength. But for the coaxial cable that connects the satellite antenna to the satellite receiver, many DSS manufacturers recommend solid copper core RG-6 quad shield because the cable must carry power (voltage switching) to switch LNBs at the antenna. Understanding the requirements for the installation are a must. Also, a telephone jack is required at each DSS receiver location. An off-air TV antenna may require one or two cables to structured wiring box and from there to TV locations. When planning external antennae or satellite dishes, make sure to take all necessary grounding, mounting, and lightning protection precautions that may be required in your region.
