Hello xm49north7 and all: I have built a few 2 element quads and modified a PDL-II quad antenna. I used 5 Ft and or 6 FT spacing for the home brew quads.

Also used 10 gauge wire for the loops not for power handling but the 10 gauge wire after market wire (Thermalized-Coated magnet wire) didn't stretch as the cheap 14 gauge wire supplied by the PDL-ll manufacture.

It would be a neat test to measure the different quad spacing and such on a calibrated analyzer, in field strength measurements to document the different spacing lengths and matching systems. Iam sure there is articles out there that show analytical (computer generated) charts of the different spacing as compared to gain and rejection. But true field strength testing and making polar plots is the way to go. Please let us know how it turns out for you.
