Hi Danny, I can't answer your original questions but I do have a few of my own for you. In reading your post I noticed that the words "<bigger>Hello DXers/contest</bigger>" are larger and bold. Also

I modelled a two-element 5-band quad with each element fed with 1/4 wavelength 75 ohm coax to a switchbox. An EZNEC model showed a bad affect on performance when the unused 1/4 wavelength lines were

Shorting a 1/4 wl line at the far end presents a very high impedance at the antenna and, opening the quad loop. An open at the far end presents a very low impedance at the antenna junction end, esse

I have juse fed all 3 elements with a common coax on a 4 element 10-15-20 meter quad. Are you saying this is bad? I am getting ready to put it back up. I use a balun at the feed point. How will this
