There are at least 3 versions.
One, is just a plain "dirt base" which looks like a short tower section
with plates welded on the sides. Bore a hole large enough for it to
fit, drop in, fill with sand and you are on your way. Another is the 3
drive in rods , and a third is a baseplate with a sharp metal wedge on
the bottom. Aligning the drive in rods can be a problem while the
metal plate is/was for temporary use like field day.
The dirt base will work fine, depending on the soil, and now much load
is put on the tower. I would not go beyond a medium size tribander. I
don't remember if they require two or three sets of guys. If I get a
chance I'll look it up later today.
