Hi-VHF Quad-Trapezoid-Loop+2Bars - OPT Hi-VHF Quad-Trapezoid-Loop+2Bars Antenna analyzed using 4nec2, formed by adding outer parts of Chireix 2-Square to an Hourglass-Loop and then adding two Horizontal Elements attached to the Balun Feedpoint. All dimensions determined using nikiml's Optimization Scripts, assuming AWG10 Wire Size (which is NOT all that critical). Hi-VHF Raw Gain = 8.8 to 9.6 to 8.8 dBi and SWR (300-ohms) Under 1.7.
