I have used a homemade water drill to install wires beneath a sidewalk and it works but it is messy.
For a ground rod, a fence post driver works just fine without the mess.

Where the soil is somewhat sandy the water drill is a piece of cake.
Unfortunately, much of northeast Ohio is clay. Very messy.
How do you install a ground rod in space?
Imagine being aboard a home-project self-launched experimental space station and you need a good ground.
In space, matched dipole or more likely pin fed waveguide. Of course at 1 mhz it would need to be 20 stories tall. The antenna would be bigger than skylab was. 🙂
Yes, KenFisher, it is true.
On a recent posting I asked about the liklihood of a medium wave signal (our AM band) escaping the ionosphere or, the reverse, a medium wave signal from space coming to earth, is considered a "no-can-do."
That may be lucky, because it rules out the need for such large space antennas.
Ya, I think you're right about dipole, which is something I know about.
But "pin-fed wave guide?" I don't have a clue. What is it?
Meaning your ground conductivity is zip point .....
At microwave frequencies a wave guide is commonly a metal conduit (usually square or rectangular) which the RF travels through instead of wire or coax.
The "pin" would be the radiator (antenna) located at the entrance to the wave guide to deliver the RF to the wave guide.
There is also an optical wave guide which uses a PIN photo diode if that was the type referred to.
