As the EDZ has gain on 10 meter would a reflector at 8 feet create more gain and also FB? The EDZ will have a bidirectional gain of about 10 dBi over ground. One reflector will give you a gain of about 11 dbi over ground with a FB ratio of about 3 dB, not really worth fooling with. However, two reflectors arranged end-to-end will give you a gain of about 13 dBi over ground with a FB ratio of about 10 dB, not too shabby. Align the center of the two reflectors with the standing wave current loops in the driven element. (current loop = current maximum point = current antinode) And what would be the effect on the other freq. will I also get some gain and FB.? Not unless you short the two reflectors together to obtain gain on 20m. Gain on the lower bands can be obtained with a loading coil between the two reflectors. Get fancy and install a motorized loading coil between the two elements (like a screwdriver). Or use two driven elements and phase them to get a beam on all bands.
