We can place our conductors vertically if we have a narrow spacing (say, ~1"), but how about using wide-spaced line (~12")? It doesn't take much imbalance to affect the F/B ratio.
I think that Harold Beverage also came up with one bi-directional design that completely dispensed with a reflection transformer and instead used one grounded wire and one floating wire. To make that work, isn't the length of the Beverage tied to the desired frequency range? (In other words, Beverages that use a reflection transformer have a much better F/B ratio over a wide frequency range.) I'd sure like to model those two designs into EZNEC+ 5.0 and see what happens, but I'm not sure how to input the transformers into the models. Has anyone ever done that? If so, I'd sure appreciate it if you'd send me your EZNEC file. :-) 73, Mike www.w0btu.com On Sun, Jul 22, 2012 at 1:38 PM, Bruce <[email protected]> wrote: > Electric Fence wire can be mounted vertically to eliminate cross arms. > > Harold Beverage ran the Belfast Beverage spaced horizontally, and > transposed frequently. > _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
