Laugh if you will but Ionce worked on a new radio transmitter tower that had excessive VSWR. The tower had four ground rods. Checking resistance between the rods when disconnected from the tower I discovered there was almost no conductance between them. It only took a tug to pull the 6" long rod from the ground. All four of them had been cut off and hammered into the ground. Seems the contractor decided it was too hard to drive theminto rocky ground so just faked it.
