My experience is to mount a 4 x 4 wooden treated post 36 inches in the
ground.
Then to use a large and long wood lag screw to go into the bottom end of a
20 ft 2 x 4 and into the post near the ground. The lag acts like a pivot
for the
2 x 4 to raise against. Then attach the mast to the 2 x 4.
Raise the mast by hand (probably with one person) and "pin" the 2 x 4 into
the 4 x 4 where the top of the post ends. Guys already attached and hook
up at ground level.
Do this on a day when wind is nill. Works great.....Steve
