I'm not taking credit. This is a minor adjustment of a Cebik design.
Seems to fit the OP's rqmts, however: no folded-dopole feed, 50 ohm matched BW of 156-162 MHz and 5-6 elements. Regards, Wes This looks like a modofied approach to an NBS Yagi-Uda. Modern Y-U design allows for a higher feedpoint SWR. Matching loss is offset by higher gain and better consistency of F/B. If no matching, then a shaped, folded dipole is used. Typically a F/B better than 22 dB (sim) is acheived with a 10% bandwidth. The design you discuss sounds more than adequate for this need though, in fact most needs. 73, Chip N1IR |
