Elevated guy anchors will do what you want if you have them properly
engineered, as I did. I totally agree with Steve. I had a PE design
the guying system, I did the mechanical drawings and contracted for
construction of the entire job. My Website shows what I did using a 10'
8" I-beam to
produce a 6' elevated guy anchor.
In fact, if you know my Website, it's intended to be a reference for
a truly engineered amateur radio antenna system - required reading
for anyone who is contemplating a new tower installation.
Today, I just processed some additional photos and will put them
up on the site tonight.
