I live in an apartment building. Around the 4th floor. My shack is
in one room and the nearest Cold Water Pipe is in the bathroom.

It would take about 20 feet of wire to go around the wall to reach
the little Cold Water pipe in the bathroom under the sink.

I am not sure which gauge of wire to buy, or must it be 100% copper?

As for clamps: What would be a good type to use? The largest thing
to clamp would be a PL259 coax connector.

What about soldering each clamps to the wire?

I have a few radios & things and maybe even an antenna that I want to
bring to a common ground.

Is their some kind of copper pipe that I could have in a horizontal
position behind the radios on my desk area, everything then clamp
down to the horizontal copper pipe, then to the 20 feet wire, then to
the Cold Water Pipe?

Is their a meter that I could also have in this line, to watch any
grounding fluctuation? I think that would be fun to watch!



A ground may or may not make any difference. It depends on the antenna
you are using. Being 40 foot off the ground the water pipe will behave
like a wire instead of ground so connecting to it is of little
consequence.


It is not so much the antena, it is the radio that need grounded. So
lets start with that.

If you have a VOM check between the cold water pipe and the ground pin
socket on the nearest electrical outlet.
this should tell you if your water pipe is grounded.
The ground pin is the D shaped hole on the outlet. DON'T use either of
the two slots the outlet
