Ch14-17 15El FD-Yagi + 14RR Corner - OPT Ch14-17 15-Element Folded Dipole Yagi with (14 Reflector Rods) Corner Reflector analyzed using 4nec2.  Dimensions determined using nikiml's Python Optimization Scripts, incl. Corner Angle and location of Yagi's Reflector relative to the Corner (+/- 10 inches), resulting in Yagi Reflector (and hence entire Yagi) being offset 7.1-in Forward of the Corner Reflector's (imaginary) Apex. Boom Length = 105-inches, , Reflector Rod Width=35.9-in, Corner Angle=40.4-deg and Xsep=8.6-in, Rod-Rod Separation (Projection onto the X-Axis). Ch14-17 Raw Gain = 18.0 dBi, F/B & F/R Ratio Min = 23.3 dB and SWR under 1.2. NOTE: BETTER than same/longer Boom Length versions with MORE Directors and Corner Rods. Date(s): 29 Sep 2013.
