Tom, I am afraid that the tree stump will rot out in a few years leaving
your tower base very unstable and dangerous.
In New York, my QTH had a solid rock shelf (Or a rock as big as Rhode
Island) down about 18 inches. The rock shelf was everywhere. To install
tower bases I dug down to the rock shelf, drilled three holes down a couple
of feet, put 1" steel rods in the holes, set up and aligned the tower base,
then framed and poured concrete around it all. For guy anchors I drilled
holes and used the expandable rock anchors. The end result was a very solid
Remember the main purpose of the tower base for a guyed tower is to prevent
lateral movement. Good luck.
