UHF 7-EL Bi-Quagi - OPT

UHF 7-El Bi-Quagi 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 (10.1 to 11.4 dBi).
SWR was excellent, under 2.0. However, F/R & F/B Ratios were fairly low (10.4 dB Minimum).

Provided only 0.7 to 0.8 dB more Raw Gain and slightly better F/B & F/R as
simpler 7-El Bi-Quad Yagi (9.4 to 10.6).
