UHF 5-Element Folded Dipole Yagi, OPTIMIZED using nikiml's Python Scripts, analyzed using 4nec2. Gain, SWR F/B & F/B performance better than CM-4040 5-El FLAT Yagi. Optimized Boom Length = 22 inches.
UHF Raw Gain = 7.3 to 9.4 to 8.9 dBi, F/B & F/R Ratio Min. = 13.4 dB (FAIR) and SWR under 3.1 (FAIR). Note well formed Azimuthal Antenna Pattern with 70-50 degree Beamwidth, deceasing with Frequency.
Nearly Bi-Directional Hi-VHF Gain = -0.5 to 0.4 dBi FORWARD and -0.4 to 0.6 dBi to REAR is slightly HIGHER and nearly OMNI-Directional. But Hi-VHF SWR (300-ohms) is Very EXCESSIVE.
PS: Jointly Optimizing UHF and Hi-VHF should improve Hi-VHF performance, perhaps at expense of UHF.
