Top of tower, a 2 meter ringo ranger, below is a 2 element circular element 6 meter yagie with a 4 element 2 meter  on the same boom.
The wagon wheel antenna was designed and fabricated by Sam.
If you have a square loop design and would like to make a circle version, then for wires fatter than about 0.1" diameter,multiply all dimensions
(that is, circumferences and element spacing) by about 0.96.
Below is a cross arm which anchors the HF wires sam uses for 10 through 80 meters.

Sam added a director to the wagon wheel for six meters on 6/2002, improved gain and directivity noticeably.
