Does an outdoor TV antenna mounted on a regular 7 ft steel fence pole need
further grounding. (It works fine for local stations).

In other words, the steel pole is about a foot into the soil, and the
antenna is bolted to it. (There's also a guy wire for stability).

This should bleed builtup charges to the ground, right?

This should bleed a lightening strike to the ground, right?


Lightening strikes are too big to bleed. If lightening did hit
something like that,I think it would melt into a puddle.

Your first qustion was on target, bleeding charges to the ground, or
call it, dispersing them to the ground. At any rate, it's too keep
something from attracting the lightening by being the opposite charge


Oops. Lightning! I've wondered about the spelling for a year or two.
Maybe I'll remember now.

(positive, I guess).

Otherwise the lightening rods on barns and houses would't work. They
are to thin and the wires going to them are too thin to carry even a
small lightening bolt.

That's what they say, at least. I don't really understand all of this.

Your pole is fine. But the problem would be the antenna elements,
which are insulated from the pole, right? Whether you are using cabel
or flat lead, there are lightening arrestors made for it, and I think
you need at least one, and maybe one at each end of the cable, the
mast and just before the house.

If more grounding is needed, how should it be done?
