There are a few options for how to install lightning protection.
Grounding the mast is easy.
Knowing how to ground or earth an antenna system can be a key factor in the operation of some antennas.
A wire from the antenna mount to a grounding source described below or a surge arrester.
The picture shows two grounding wires attached to the antenna.
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.
