Ground and static protection question

Post by TommyB » Fri, 12 Sep 2003 22:51:00

I'm going to build some static protection for my outside wires and I
was wondering about what kind of ground is required. These are just
random wires that  that will be connected to my antenna switcher which
then connects to the push-connecter of my R75. No coax.

Can I use the house's electrical ground (i.e. the ground from a nearby
outlet) or do I need to pound copper? Would using the ground from the
outlet introduce noise or any other problems?

BTW, I'm using as my model the simple neon bulb, resistor, capacitor
schematic that I found on hard-core-dx .

Thanks!

I think that an actual connection to a metal rod pounded into the earth is
best whenever possible. Nowadays, plumbing can consist of PVC pipe which is
not metalic and won't work, so you have to be careful about that. I've read
of using a heavy duty mesh or screen of copper metal buried under the earth
can work also. I'm not sure you would get what you actually need by using
the grounding plug of an electrical outlet.

TB,

FWIW:  If you have an outside Antenna,

IMHO:  Then you need an outside Ground.  

TIP: Put as "Much" Planning, Time, Money and Effort in to your
Grounding System as your Antenna System.

The a.c. ground acts like an antenna for me. It picks up signals induced off
the hot wire (not considering the effect of the parallel neutral wire).

Soil type makes a difference, too. I heard of a guy in the desert using an old
hot water heater filled with rock salt, its sides punctured (Using a gun? I
don't know. <G>), and then buried. An extension pipe provided the electrical
connection as well as a way to fill the tank with water. It then seeped salty
water which spread.
