UHF 13-El FD-Yagi (2ReflRod) - OPTimized UHF 13-Element Folded Dipole Yagi (with 2 Reflector Rods), Optimized using nikiml's Python Script and then analyzed using 4nec2. Boom Length = 40.2 inches. UHF Raw Gain = 9.3 to 13.4 dBi, F/B & F/R Ratio Minimum = 22.3 dB (EXCL) and SWR Under 1.7 (GOOD). Provides a significant improvement in F/B & F/R relative to 12-El FD-Yagi with only one Reflector Rod. Boom Correction Calculation Examples are given in the below Spread Sheet, based on a variety of sources. For a 1-in Boom (Circular or Square), the extra Passive Element Half-Length is 0.25-in or LESS, and for a 1/2-in Boom, the Boom Correction is only 0.1-in or LESS. Date(s): 6 Jul 2013.
