[Elecraft] Has anyone used an Alpha Delta DX-40/20 Antenna??

[Norm Klieman]

Has anyone ever used an Alpha Delta DX40-20 antenna?
A friend of mine is going to let me use it over the 
winter months with my K1. What I wanted to find out if
anyone has used this as a sloper and how high off the
ground did you have the end or did you just angle it
directly with an anchor into the ground. I am
considering also running it as an inverted vee but
again need to know if it has a specific requirement if
the ends have to me a certain height off the ground.
Any other comments on this antenna are welcome to!
