Assuming that sufficient tower height was available, guy wires are insulated or broken up into short non-resonant sections. Tower face is 12 or 18".

Start at 1/4 wave up with a 1/4 wave ground plane with radials sloping at about 45 degrees. The vertical wire is 6-12' away from the tower face.

Then a 1/4 wave (or 1/8) up install a duplicate.

What does EZNEC say about this?

With the different spacings?

Effect of starting lower and how low before there are ground related problems?

Phasing with coax or a LC network?

Switching in a delay line to tilt the lobe up a bit?

Curiosity got the cat!
