Ok, I am building a 2 element quad for 11 meters. I have checked many building plans, and many online calculators. None of them agree. For the spacing between driven element and reflector, I get everything from 3 feet to 5 feet to 8 feet, I get a number saying 62 inches and 63 inches, 67 inches. Some say longer the better for gain ,I would welcome any experience, thoughts, modeling info. I have most of my parts made, just deciding on boom length to start with, more interested in gain, than front to back, as where I live in rural area, there is no back traffic at all. Majority of my contacts are in a south to west zone. Thank you in advance, for those who wish to jot down there thoughts. I am using 27.200 mhz for my calculations (channel 20) Also this will be a quagy design, my loops are aprox. 6 feet wide by 12 feet tall, made from #14 stranded copper wire and driven is middle side fed, for vertical polarization. This will be top hung from a wood boom, On a wood pole. at 30 feet to the top boom to start .
