  He also knows that a long BOG antenna will self terminate, but not at an ideal termination impedance. Also knows that a BOG antenna is a one band antenna when referencing a nice front to back pattern. He missed his calling. Should have a professor at Harvard University.   73 Bruce-K1FZ

Sorry for getting in on this late. Various forms of wife-inspired busy-ness. The real kicker here isn't the pattern, it's LOSS. It is helpful when mentally eyeballing an installation like this to see it in *wavelengths* rather than linear feet. The distance that a dielectric material can be from

A cloud warmer pattern can more easily be achieved with just a simple wire dipole for topband . If space is a problem folding back the far ends or vertical drop wires of the high voltage ends should easily deal with that issue. On 5/24/2016 1:02 PM, GALE STEWARD via Topband wrote: Totally ag
