I've used a couple different types of anchors and they work very well. I've
never seen a place with soil composition that allows one to screw in an
anchor. Maybe if you have 6 feet of topsoil or sand, that would work.
I've used an anchor that had a multi-piece mechanism that looked like a
flower with petals retracted. I dug a 6" diameter hole at the right angle,
maybe 5 feet deep, and inserted the thing in the hole. You then set the
anchor by putting a pipe over the rod and driving the end piece that sits in
the bottom of the hole. That causes the "flower" to open up and pulling on
the rod causes it to try to open further. They carry pretty high pulling
force ratings and are commonly used on utility poles. I bought mine from a
company that carries line hardware and think maybe the manufacturer of the
anchors was AB Chance. Their website should have all the details.
