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.
How to ground antenna on roof.
When looking at how to ground an antenna it is necessary to look at what is required and then proceed accordingly.
Ground that point if possible.
It s recommended to use a separate clamp and not the one used to ground the coaxial to the house ground.
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.
There are several aspects to grounding an antenna.
Grounding an antenna properly makes the antenna safe to use and also enables the best to be made of the performance of the antenna.
Grounding the mast is easy.
Grounding the coaxial was the hard part.
Run a braided wire from each piece of equipment to a common point.
A wire from the antenna mount to a grounding source described below or a surge arrester.
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 an antenna.
Never shorten the ground rod because it is difficult to hammer into the ground.
To protect yourself from a direct strike attach a lightening arrester to the antenna mast.
To ground the mast of the antenna follow the manufacturer s instructions on where to attach the ground wire.
Again the clamp you will need will depend on the diameter of your antenna mast.
Ground the antenna mast.
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.
Ground poles or ground rods can be purchased at an electrical supply center or home store.
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.
One is attached to the mast or pole on which the antenna is mounted.
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.
There are a few options for how to install lightning protection.
The best thing one can do to prevent stray rf is to connect the grounds of all equipment together and at a common point.
The picture below from the national electrical code sums it up well.
The picture shows two grounding wires attached to the antenna.
