intentions are good, and appreciated, but w/o knowing
the type of ground someone has your advice may or may
not be of much help. I will share a story about my quest
to drive in about a dozen 10' long ground rods each 5/8"
dia steel, heavy copper coated into very nasty hard
method I tried resulted in total failure &
frustration. This back when I was healthy and thought
nothing of swinging a 10 pound sledge hammer all day. My
ground here in NE Indiana is some form of horrible nasty
good for nothing clay/shale mix. You can get a rod
pounded in about 2' with great effort and then all you
will do is mushroom the top of the rod and end up with a
sore back with an 8' rod sticking out of the ground that
cannot be removed. My 2 acre pond holds water very well.
every trick I had ever heard of w/o success. Tried
beating the crap out of it with every hammer I owned, no
luck. Tried the heavy steel pipe with massive metal cap
and handles, same results. Tried a 3/4" conduit pipe
sharpened at the tip and a garden hose attached at the
top with a hose clamp (and water turned on full flow)
and repeated thrusts up & down hoping to make a
water drill, zero luck and a huge mess. Tried to fill
the started holes with water and let them sit for
several days to loosen up the crap below.....the water
level NEVER went down.
did end up using that worked like a gift from heaven was
renting an electric jack-hammer that weighed about 80
pounds and stood 3-4 feet tall. You remove the huge 10
pound steel bit that normally goes into the hammer and
you are left with a nice 1.5" dia hole maybe 8" deep
that fits very nicely over the top of the ground rod. I
sat up a step ladder next to the rod, lifted the
jack-hammer up over the ground rod and let it rip. The
ground rod drops in length like magic just from the
weight of the hammer slamming away. Total time per rod
is about 5 minutes. If you have normal soil those other
techniques may work but if you have this crap we have
here called ground then the jack-hammer is the only way

Dribble a hose where you want the
ground rod to go in overnight with a very slow dribble so
the ground absorbs it well. Then push the silly thing in
with your hand unless you have very rocky soil. In that
case the ground rod is never going to go in nicely.
The approved tool is a 2' section of galvanized pipe with
a cap on it. That will drive it in straight with modest
effort. At least that's what I am told. I used the dribble
technique and the rod went in like a warm knife into warm
butter. It didn't quite sink on its own. I live in a
former flood plain for very serious storms. (As in 1969
shortly after I moved into Ca we had Cosby weather. "Let
it rain for 40 days and 40 nights until the sewers back
up." We desperately need that sort or weather again.)

At this juncture I should point out that I did not ground
my installation by conscious choice. I actually have an
8-ft ground rod and was prepared to get everything
properly grounded, but I just never got around to picking
up the hammer drill to drive the thing into the ground.
It's a good thing too, because I'm about to move all of my
equipment to my other QTH we're grounding should be much
easier to accomplish.
My plan is to properly ground and bond the station.
