Just as a precaution, I would measure the amount of anchor rod above the
surface and
check it periodically, just to make sure the anchors aren't slowly pulling out
of the
ground. If the tower can sink, I would be concerned about the long term effect
of a
constant pull on an anchor in the same soil. I may be all wrong here, but it
doesn't
cost anything to check it once in awhile . . .
