Here is another similar way to do it with a 50' aluminum tower. We have since
added an additional 10' section of tower and put an A4 on top without any
problems.

This is a well proven method.
I have a very similar setup that I have been using on Field day
for a number of years. I also used four 3/4 inch rods
into dirt for my homebrew tilt base. Instead of using set
screw collars, I simply use 1 inch holes and pound in the rods at
an angle, so that the plate cannot lift up. My tower is aluminum, so I
don't even need a winch. I use a pulley at the top of the derrick to
get a 2:1 mechanical advantage. The derrick is 30 feet
of aluminum tower that I happened to have; probably overkill.
