UHF Quadazoid Loop - No Refl
UHF Quadazoid Loop (No Reflector) analyzed using 4nec2 after determining "best"
Dimensions using nikiml's Python Optimizer Scripts.  ["Quadazoid" = Quadruple Trapezoid.]

UHF Raw Gain = 6.3 to 7.4 to 6.2 dBi and SWR (300-ohms) Under 1.7.
UHF Beamwidth = 82 to 72 degrees, Bi-Directional, decreasing with Freq.
