It's ridiculous to draw an equivalence between a lattice tower
properly resting on a pier and pin with a telephone pole, that is
solid wood, and in the ground 10 feet in a tight hole made with an
auger. Wood as a material behaves in a completely different manner
under stress. Phone pole guying is usually done to counter the pull
of power cables at the end of a line or when there's a change in
direction. Otherwise wood poles are usually unguyed. A tower on a
pin has to be guyed just to remain vertical. A wood pole won't
collapse from being sunk into the ground. A tower will unless it is a
short stub
