    Grounding:

    In an electrical system, ground loop refers to a current, generally unwanted, in a conductor connecting two points that are supposed to be at the same potential, that is, ground, but are actually at different potentials. Ground loops can be detrimental to the intended operation of the system.

    Low current wiring is particularly susceptible to ground loops. If two pieces of audio equipment are plugged into different power outlets, there will often be a difference in their respective ground potentials. If a signal is passed from one to the other via an unbalanced connection, this potential difference causes a spurious current to flow through the cables.

    How to properly ground your system:


    1. Attach the grounding block(s) where all cables can be attached, so grounding point will be common for all the receivers in your system. You may have to use anchors, togglers, or wood screws depending on the surface on which you are mounting the grounding block.



    2. Route the coaxial cable and ground wire to the grounding block. If the ground wire is not isolated then ceramic isolators should be used to route it. Different reference grounds to different LNBs, switches, and receivers in the sytem, can be accommodated by tying these references to a common point (in plain English: use a common ground for all your devices).

    3. Make a 3"- 5" drip loop using cable clips at the grounding block. This will prevent water from running into the connection at the grounding block.

    4. Secure the ground wire to the grounding block with the screw.

    5. Route the grounding wire from the grounding block to the central building ground, and connect to the central building ground or service pole.

    NOTE:This is info I found at another site!Hopefully it will explain a little better and help to answer questions members may have concerning this.
