Mine started to lean just a bit several years ago having
been in the ground over 20 years. No worries, I just
hooked on 3 "come-along" winches, then dug a hole
next to the hole that has the sand, washed out enough
sand into the new hole so the tower was "loose".
Adjusted the winches so the tower was perfectly vertical,
then back-filled with more sand. Easy job, really.
> Wonder ground post sinks into the ground?
No sinking noticed here. It has a metal base plate
maybe 18" square. Install on undisturbed earth.

No, they are solidly braced. IIRC, braced fin-to-fin.

No, mine hasn't. Setting it in sand may have had something to
do with that.

IMHO, YES!! Hot-dip galvanize it too.

NO pounding! :D) Dig the hole in earth, lower the post in the
hole with a guyed, wood "A" frame equipped with a winch. Fill
with sand and wash the sand in with water. Use the
finest graded sand you can get like the type that is
used for brick morter. NOT the white silica sand, "play"
sand or beach sand.

It works for me. I've used that sand method for fence posts
and many other poles/posts. Never a problem here. Always
wash it in with water so it leaves no voids.

A large concrete block would have more resistance
to over-tuning, but it may be way more than what is needed depending
on the soil.
