Grounding of outdoor Antenna

Post by HDRob »

I had an antenna when I purchased my house 11 years ago that had been placed in an oak tree probably 30 years ago. It used the old two wire coming into the house and we were able to receive several channels from it. The house is about 35 miles from the main sources. I live in NJ and am 35 miles from NYC. I had to take the tree down for specific reasons and of course lost my antenna. I have since purchased Channel Master's largest antenna Crossfire model 3671 and have mounted it to my chimney. I also purchased the Channel Master rotor model 9521A along with their Titan model 7777 amplifier. One question I have is since I have the rotor if I connect my ground wire to the mast below the rotor will that be sufficient or should I connect it to the mast that turns. Of course connecting it to the mast that turns could be a little tricky. If lightning strikes the antenna and I have grounded it to the lower mast will it conduct from the upper mast to the lower mast through the rotor. I have put a 4 foot grounding rod into the ground at the base of the chimney for the grounding purposes. I was looking at this site for what they were saying for grounding http://www.hdtvprimer.com/ANTENNAS/basics.html .

By the way this is my first time putting up an antenna so if any of you have any other good advice please feel very free to give it to me. If anything I have said sounds like I have done something wrong then please feel free to correct me. I would rather do it right and have it work properly rather then suffer with a bad signal because I did something wrong.

Thank you for your help in advance.


Sincerely,

Rob

Rob- Grounding the lower mast is the standard practice. The upper and lower sections are not insulated from each other. -Ken

Ken,

So there is a connection between the upper and lower mast through the rotor?

As Ken said, the sections are not insulated from one another...

or, stated another way...

The whole thing's metal. Grounding the lower section covers it all.
