Grounding block question for Antenna install

Hello All!

I have a question on needing grounding block for all wires coming out of signal booster or in between the main cable from antenna into the booster? Does anyone know which would be the proper way to ground? I appreciate any and all answers or help!

Thank you.

In general, the ground block should be placed where the cable enters the building. While some local codes might have more specific requirements, typically your grounding block should be tied to the same point as your electrical ground. This would be driven rods in the ground, or possibly the cold water pipe on the street side of the meter. Go right to the grounding source; don't connect to conduit, electrical fixtures, the breaker panel, or interior water pipes. In some cases, you can drive a new grounding rod... but a proper job requires test equipment to ensure that the rod has an acceptably low resistance to ground.

The wire itself should be reasonably heavy -- at least #10 gauge -- and can be uninsulated. Avoid sharp bends, and clearly tag the end at the ground point. If your house has a traditional phone line or a cable TV feed, you should be able to use its grounding wire as an example of where and how it should be connected.
