that's a fairly popular way to do bases of things (traffic lights, etc.)
here in southern California: minimum disruption of the surroundings,
and compatible with working on a hillside. Historically, it's been more
expensive to have a tall skinny hole drilled than to have a big cube
dug, but that changes.
You need to figure out how deep to drill, too. That depends on what the
function of the base is. A guyed tower is resisting down forces mostly,
and a little bit of shear. A self supporter has overturning forces
trying to lever the base up out of the ground.
