How To Ground Roof Antenna

The picture shows two grounding wires attached to the antenna.

How to ground roof antenna.

One is attached to the mast or pole on which the antenna is mounted. Using an antenna mast ground clamp run the other end of the ground wire you connected in step 2 to your antenna mast and secure it tightly. In electrical engineering to ground something means creating a direct physical connection between an electrical circuit and the earth. The picture below from the national electrical code sums it up well.

To protect yourself from a direct strike attach a lightening arrester to the antenna mast. It s recommended to use a separate clamp and not the one used to ground the coaxial to the house ground. Step 3 how to properly ground a tv antenna mast. How to ground a tv antenna you can t just tell it to go to its room.

Knowing how to ground or earth an antenna system can be a key factor in the operation of some antennas. Grounding the coax cable with a coaxial lighting surge protector will protect your equipment from voltage surges created by nearby strikes but not from a direct strike. Knowing how to ground an antenna properly can make significant improvements to its performance whereas a poor ground or earth connection can mean that its performance is greatly impaired. The other is attached to the antenna coaxial cable.

Simply attach an 8 or 10 awg copper wire to the mast using a mast ground clamp and run the other end of the copper wire to the house ground. Grounding the coaxial was the hard part. Generally if you have a metal antenna mount on your roof that is over 5 feet tall you will want to ground that using a long copper wire. Again the clamp you will need will depend on the diameter of your antenna mast.

A wire from the antenna mount to a grounding source described below or a surge arrester. Step 4 how to ground your coax cable. Both these wires terminate or are joined together at a place referred to as the power service grounding electrode system located at. There are a few options for how to install lightning protection.
