UHF 7-El Bi-Quad Yagi - OPT
UHF 7-El Bi-Quad Yagi Merger analyzed using 4nec2.
Dimensions were re-determined by using nikiml's Python Optimization Scripts.

Raw Gain frequency response is flatter than nikiml's Optimized 7-El Folded Dipole Yagi,
with higher Gain on lower channels and lower Gain on upper channels (9.5 to 10.6 dBi).
SWR was excellent, under 2.0.  However, F/R & F/B Ratios were fairly low (10.4 dB Minimum).
