TV Antenna Grounding

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.

This is part 1 of 4 on the installation of an outdoor TV antenna. The other parts and the results videos, coming soon. Antenna Info: Brand ...

I want to run a ground wire to my tv antenna on the roof. I have plenty of copper wire that is coated. Can I use this coated wire or does ground wire have to be bare.

coated is fine, just peel back the cover on both ends. Copper is the best conductor and won't rust.

I installed an antenna on my roof. I am running an insulated copper wire from the mast to either a galvanized steel or an aluminum rod (not sure which - I got it from my neighboor who is an HVAC worker) driven about 5 ft into the ground. The coaxial cable from the antenna is run into a grounding block which is also grounded to the same steel (aluminum?) rod by insulated copper wire. After the grounding block, the coaxial is then run into a splitter used by the cable company in a box outside my house (from when I used to have cable). The cable company's splitter is attached to some sort of grounding plate which has a short copper ground wire attached to my electric box. Coaxial cable is run from the splitter and into my house at two different locations, each about 10-15 ft from the splitter.

Does this sound like it is properly grounded to bleed out static electricity build-up? Any concerns about grounding it to two different places (rod and electric box)?

Well its seems your TV antenna is properly grounded and also try to put tape on your grounding block for water insulation.

I'm installing an outdoor tv antenna, the directions say run a ground wire from the base of the mast of the antenna to a grounding source. I will be using a Grounding Rod. What I need to know is this, I'm using Screw Standoffs to keep the cable wire from touching or resting on the roof, can I also run the (insulated) Grounding Wire thru the same Screw Standoffs, side by side? I want to run both of these to the Grounding Block, and then run the Grounding Wire thru the Grounding Block down to the Grounding Rod in the ground. I think I've read somewhere that the Grounding Wire and the Coax Cable must be at least 2 feet apart, is this true?
Thanks for answer, I appreciate it, One more question though, Can I run the two wires 2 feet apart but then only let them meet up at the Grounding Block. I'm a little confused, doesn't the Grounding Wire have to go thru the Grounding Block, or can I just run it to the Grounding Source?

Yes, what you read is true. The reason for it is if lightning hits the antenna it SHOULD go through the grounding block, down the ground wire, and into your grounding rod. If the coax is too close the voltage may arc back to the coax and you would know what your TV set looks like when overcharged.

Side note: Grounding to your main electrical box is better than a 6 foot grounding rod. The infrastructure that you would ground to on the electrical grid can handle alot of power and is designed for this. Thats what your cable guys ground too.

Ok so you have an antenna up in the air on a pole. You need to run a coax (or twin lead wire) from the antenna to your grounding block http://www.radioshack.com/product/index. jsp?productId=2150597&cp=&sr=1&a mp;origkw=grounding+block&kw=groundi ng+block&parentPage=search which is attatched to the pole, grounding the pole through contact from the base of the grounding block. Off the other end of the grounding block you then run the other Coax to your tv's... Now you need to run a ground wire from the ground block (the right side of the picture, unscrew the screw slide in wire tighten screw) to your ground point. This doesnt even need to be close to your coax at all and can go in a completely different direction.

This gives a better ground to your pole http://www.radioshack.com/product/index. jsp?productId=2150592&cp=&sr=1&a mp;origkw=grounding+block&kw=groundi ng+block&parentPage=search as it is curved on the base to match the curve of the pole.

Those arent the best pictures. The blue part is where the coax goes in, with the little hole in the center where the center of the coax goes. The pic doesnt show the threads. If you go to a store and see one in person it will make sense.
