If the conduit is metalic, and at least size 3/4″, and at least 8 ft. long. Then you should be able to use it as the grounding electrode for the antenna. If the conduit meets all these criteria, then you’ll want to bond the antenna mast to it using at least 10 AWG solid copper wire (810.21(H)).
How do I ground my antenna?
Quote from the video:
Quote from Youtube video: Use the ground block to connect the coaxial cable from your TV antenna to another coaxial cable that's going into your house.
Can you ground antenna to electrical ground?
Grounding the mast is easy. 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. It’s recommended to use a separate clamp, and not the one used to ground the coaxial to the house ground.
Does antenna need to be grounded?
You might not know that the National Electrical Code (NEC) requires every TV antenna to be grounded. Why? TV antennas that aren’t or are improperly grounded can lead to house fires from lightning strikes. Improper grounding also can cause lighting to enter your home!
What happens if you don’t ground an antenna?
So grounding the antenna, drains off any charge that might build up attracting a strike. Also an ungrounded antenna, that builds up a charge, can cause silent damage to your equipment, as this charge will discharge down your coax when it builds up a high enough potential, and do ‘silent’ damage to your TV tuner.
Can you use PVC for antenna mast?
PVC conduit has one flared end which works well for this project. The flared end should be at the bottom of each section in order to keep water out of the mast in wet weather. The very bottom section is made from a piece of PVC with no flare. The total length of this mast is 20 feet.
How do you ground a RF antenna?
Quote from the video:
Quote from Youtube video: Very often there is a little some place where you can attach a ground wire failing that wrap it around the outer connector of the coax. Something like that. When you have wire antennas.
Do antennas attract lightning?
Outdoor antennas that aren’t properly installed can attract lightning into your home and start a fire. They can also indirectly attract voltage from nearby lightning strikes that can fry your TV and other electronics, experts say.
How do I protect my antenna from lightning?
To completely protect your device from lightning, two layers of protection are recommended: installing an in-line lightning surge arrestor and grounding the antenna mast.

- Summary.
Why do antennas need a ground?
Grounding will eliminate static electricity, as well as protect against energy to the mast if the antenna comes in contact with live electrical wires.
Does a grounded antenna attract lightning?
It is a common belief that antennas attract lightning. But is it true? TV Antennas are a good conductor of electricity, so they could certainly attract lightning. During a thunderstorm, anything conductive that is not grounded will gather a static charge; as this charge accumulates, it naturally attracts lightning.
Do I need to ground an antenna in the attic?
Attic mounted antennas do not need to be grounded, only outdoor. Grounding bleeds off static charge from air passing over antenna – not an issue with attic mounted antennas. Proper grounding and bonding will limit potential damage due to surges from nearby lightning strikes.
Why should a ground wire be connected to the metal support rod for a television antenna?
The antenna is similar to a lightning rod and can induce a bolt to strike it. A wire from the antenna to the ground provides a pathway for the charges to move away from the house in case a lightning strike does occur.
What can I use for antenna mast?
Non-steel options
If you’re worried most about the mast itself actually interfering with the reception pattern of the antenna then you’d probably want the mast to be something non-conductive but as strong as possible. Carbon fiber would probably be a good material for this, or if you’re feeling less exotic, fiberglass.
How do you make a homemade antenna mast?
Quote from the video:
Quote from Youtube video: At the center of the platform. We have two u-bolts that are going to actually hold the pvc of the antenna to the platform. So that will brace it to the platform.
Can an antenna mast be metal?
Quote from the video:
Quote from Youtube video: And it works just fine the metal mast for supporting the elements is where you have the problem the problem is because this piece of metal mask is an antenna in and of itself.
What is the best material for a mast?
Sitka Spruce (Silver, Tideland or Menzies Spruce) has long been the top choice for mast builders.
Do you need to ground a fiberglass antenna?
The antenna does not require to be grounded. But to protect your device from lighting, you can use a Lightning arrestor and a Grounding Wire to ground the arrestor.
How do you make a crank up antenna mast?
Quote from the video:
Quote from Youtube video: I took and cut a 1 foot section of split. It down the middle so it was smaller. And then stuffed it inside.
How do you make an antenna tower?
Quote from the video:
Quote from Youtube video: And that's actually what i've done today put it about three three and a half feet in put 150 pounds of concrete down in the hole with it mix it up pour it in there and it's setting.
How do you install a telescoping antenna mast?
Quote from the video:
Quote from Youtube video: To prepare the top segment for installation secure the guy ring approximately six inches below where you'd mount the antenna using the mask lamp with Expo. When it comes time to extend the mast.
