Hi, Joe.
There are several kinds of electric fence wire. I just bought a spool,
1300' or so, of aluminum wire. There is electro-galvanized steel,
also. The electro gives a smooth coating, but doesn't last.

What might be better is the stainless steel wire used to wrap
telephone cable and cable TV cable to a messenger wire suspended from
poles. If you examine such a line carefully, you will see the spiral
wrap of wire holding is all together. The installers use a sliding
wrapping tool with a spool of the wire spinning around the cables as
they pull it along from the ground.

Several years ago my neighbor gave me a spool of it he found along the
road after the installation crew went through with new cable. The
spool was a rats nest of wire. So, they must have discarded it rather
than take the time to rewind it. Anyway, it is about the same diameter
as fence wire.

I suspect if you see either the telephone or cable TV installation
crew, you might ask if they had any unusable wrap wire. Might get it
for free!

Good luck with the project.

Thanks all
It looks like I can get my shack up and running long before my home will be
ready (thanks to solar power) I own an acre of land next door to my parents,
that's where we will be staying while the new home is in the works. It bytes
but I need the money from selling this home to get moving on the new one.

Anyway, I have 90% of the hardware needed to get my shack up and running. I
just need 3 more sections of tower (the shed itself, but I will build that)
I screw everything together except the shingles (no nails)
Glue it and screw it!
I also need a temporary, rf ground system (something that I can install
fast and cheap. I will also have some kind of metal fence up, welded wire /
chainlink, that I will tie into it....
The land is in NC near Jacksonville, I have no idea what the PH is but from
the pine trees on the lot (they are being removed to let the hardwoods grow)
I would say a slightly acidic soil.
There is nothing on the lot at this time so I get to start from scratch.

Family members also own 1 acre of land on each side of me (north to south
with me in the middle) and also 5 acres behind me (north of me, right behind
my lot and 5 acres wide north to south) so I have plenty of room for wire
antennas etc. I just need to preplan everything possible. Once everything is
in place that is where it will stay.

How would you lay out a ground system for both RF and lightning on a
budget? Something that could start out with say, electric fence wire and be
replaced with copper over time?

If I need to bond two dissimilar metal wires, I do it down and dirty. Lets
say I want to bond a copper ground wire to a galvanized tower leg.
I tighten one Stainless steel hose clamp on the tower leg, place the wire
over it and tighten up another SS hose clamp over it, so the connection has
SS between the different metals. You can also do the same thing with SS nuts
and bolts, just make sure the different metals have SS between them. Seems
to work well for me.

Sorry for the long post...I will lose internet when I move for a while so I
have a lot of questions....

A good system of ground radials serves both purposes well.

Lay off the fence wire. Magnesium, aluminum, and zinc are likely to
deteriorate papidly in the soil. Copper is likely to last forever.
