A wire from the antenna mount to a grounding source described below or a surge arrester.
How to ground antenna on roof.
To protect yourself from a direct strike attach a lightening arrester to the antenna mast.
One is attached to the mast or pole on which the antenna is mounted.
The picture shows two grounding wires attached to the antenna.
Run a braided wire from each piece of equipment to a common point.
There are several aspects to grounding an antenna.
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.
Ground poles or ground rods can be purchased at an electrical supply center or home store.

The ground rod must be deep enough to discharge any voltage.
A copper rod driven into the ground with an antenna on the roof is especially not an rf ground.
How to ground antenna.
When looking at how to ground an antenna it is necessary to look at what is required and then proceed accordingly.
Both these wires terminate or are joined together at a place referred to as the power service grounding electrode system located at.

Step 4 how to ground your coax cable.
Ground the antenna mast.
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.
