How would you drive in a rod that is 17 feet long? It's a bitch
driving in a 10 footer at times. You got to get on a ladder and then
the think likes to bounce around as you sledge hammer it down.
10ft. is plenty, and in most areas, the NEC requires at least 2 rods
spaced at least 10 ft apart, then bonded together.


It would make more sense to couple two rods somehow. Drive one in, put on
the coupling, then the second rod.

I imagine they don't make extra long ones because they are not needed, not
practical.




They make sectional ground rods; the ends are threaded (including the
pointy end), and thet have special couplers and a driving stud so you
don't bugger the threads when you pound on them.

But last time I checked, 3/4" (or larger) galvanized water pipe or RMC
is NEC approved for use as a made electrode, and can be had in 20'
lengths without needing a coupling. I would drive it using a ladder and
a T-post driver rather than a sledgehammer.
