Rick, I beg your pardon - the radiation of an antenna has everything to do with the relative phase. That is what creates gain and cancellation in the radiation pattern. The phase addition or cancellation on a long wire or any other antenna for that matter is what gives rise to the radiation pattern.
A half wavelength antenna will have radiation perpendicular to the wire, a full wavelength wire will have 4 lobes each at 45 degrees angle to the wire, a 3 wavelength wire will have 6 lobes spaced at 60 degrees (30 degrees from the wire to the first lobes), a 4 wavelength wire will have 8 lobes 45 degrees apart, and so forth. A "V" antenna or a rhombic derives its gain in a bi-directional lobe by depending on the cancellation and additive effects of two wires and is manipulated by the angle between the wires. I know of no case where the maximum radiation is parallel with the wire (off the ends). 73, Don W3FPR [email protected] wrote: > Hmmm... isn't a definition of a "long wire" one in which alternate half > wave > sections are out of phase?
