Antenna Mast
Are Grounding Blocks for a Tv Antenna Coax Cable necessary? What can happen if Coax is not grounded?
I have a good idea how to ground the Antenna itself. I am going to run the copper #6 wire from the antenna mast to the ground spike below.
Or I could run it around the house to th ouside spike already there.
I am pretty sure my Tv antenna guy did not ground the coax with a grounding block.
You are correct, the mast needs to be grounded for lightning protection. Use a heavy gage copper wire and route it to a grounding rod. Make sure there are no sharp bends in the wire and keep it as short as practical.
A grounding block is also a good idea to protect the input to the TV. They are inexpensive and should also be connected to a grounding rod via a wire with no sharp bends.
Not grounding your antenna and down lead will invite lightning damage to your house and electronic equipment.
