Tom,
All of the dimesnions, including the location of the couplers from the center
are on the Array Solutions Website in the SAL v 1.9 manual at:
http://arraysolutions.com/Products/SAL_shared%20apex%20loop/PDF%20Files/AS-SAL-Manual_R1.9.pdf
Mine is the SAL-30 with the 95 foot loop. I would say the mirror dimension is
about 1.5 inches, or 3 inches between the vertical wires. My 4 NEC2 model shows
8.64 dB RDF.
Thanks for your interest,
Bruce W8RA

Regardless, I am not sure if any sort of "descriptive logical explanation" will
ever allow me to understand what is going on with this antenna but I am
beginning to get comfortable with the modeling. The bigger question to me is;
do you think the 4NEC2 model results faithfully represent what is going on with
this antenna?>>>
What are the dimensions of your antenna? Just one loop will work, if they are
identical, and the spacing to the mirror.
