HiVHF 8-El Crossed Dipole-Pair Yagi Hi-VHF 8-Element Cross Yagi with Right Hand Circular Polarized (RHCP) Dipole-Pair active driver elements analyzed using 4nec2.  Dimensions of K6STI's  Dipole-Pair (w/o Yagi) were optimized using nikiml's optimization scripts, presuming QICT (Quarter-Inch Copper Tube) element size. Although Gain, SWR & RHCP were very good across Ch7-10, Cross Polarization Loss was only good on a limited range of frequencies. Since the K7MEM designs are NOT optimized for wide-band use, usable Gain is only realized on Ch7-10, with reduced F/B and F/R Ratios on Ch7. Date(s): 3 Feb 2011.
