1. Coaxial Cable
    1. Signal loss and cable length

      2. All cables for satellite L-band I.F. must be 75 ohms. The satellite I.F. band is between 950 and 1,450 MHz.
       
        Loss per 100 feet at 1,500 MHz Max Length without an amplifier
      RG-59 11 dB 150 feet
      RG-6 8 dB 200 feet
      RG-11 5 dB 330 feet

      Do not use "video cable", even if labeled "professional." It has even higher loss than RG-59.

    2. Splitters
      1. Allows you to put more than one receiver on the same LNB cable.
      2. Splitters are OK, but each 2-way split adds almost 4 dB to system losses unless an amplified "lossless" splitter is installed. Equipment houses sell them.
      3. Don’t use $5 splitters from home centers or electronics stores which are intended for use with over-the-air TV antennas or cable TV systems. L-band satellite systems use higher frequencies than the highest TV channel.
    3. Correct connector installation
      1. Crimp connectors properly
      2. Weatherproof connections properly

        3. Use rubber "boots" or "clay tape" which is packed with some connectors or LNBs.
    4. Routing coax line
      1. OK to direct-bury (if cable is rated for it) but not under roads or parking lots.

        2. Best to put cable in metal or plastic conduit. Allows installation of new or replacement cables without digging again. Keep water out of conduit; if it freezes and expands, it will crush the coaxial cable.
