Just mount the yagi on a metal mast and run a clamped on wire from
the bottom of the mast down to a rod driven into the ground. If you
want to use a wooden mast then just clamp a wire to the boom or
the mount of the antenna and run the wire perpendicular to the boom
and away from the antenna down the wooden mast. The ground driven
rod is ideally eight foot long but it is unlikely you'll be able to
use the full length. If possible drive the ground rod close to
grounded plumbing like your outside water spigot. Attach a short
jumper to the plumbing also.

This is the ticket. I'll do it this way. Best compromise between safety
and signal quality.

Not according to the NEC, which requires an arrestor on the cable and
doesn't have a compromise. What you are proposing grounds the
antenna mast, but leaves the antenna itself with no protection. If
there were even a nearby lightning strike, the antenna could wind up
with thousands of volts and that energy is going to go down the coax
and into your cell phone.

Every outside antenna installation picture from manuals and similar
I've ever seen shows both grounding the mast and using an arrestor on
the cable where it enters the building. Did you look in the
instructions for the antenna you have?







Couple of more questions then....

I'll be running the wire down the outside of the house, over metal siding.
Will need to bolt/clamp it to the side of the house since it will be a 10' +
run. Do I need special clamps to try to keep the wire off the wall?

Also, what gauge wire is recommended? Is there a special designation for
grounding wire that the folks at the supply store will know (and obviously I
don't).

Thanks again
