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

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. _________________ Topband Reflector Archives - http://www.contesting.com/_topband
