Lo-HiVHF (Ch2-13) 1-Bay Bowtie analyzed using 4nec2 after optimizing via nikimil's Python scripts.
NO REFLECTOR RODS: Ch2-6 Raw Gain = about 3.5 to 5.0 dBi and SWR (300-ohms) Under 2.7. Ch7-13 Raw Gain = about 4.0 to 5.0 dBi and SWR (300-ohms) Under 2.7.
Provides more Gain than Stick Dipole or Folded Dipole across BOTH Ch2-6 Lo-VHF and Ch7-13 Hi-VHF Bands. However, narrow beamwidth on Ch7-13 requires careful aiming.
Optimized size is BIG (15.75-ft Wide by 4.25-ft High), using 1/4-in O.D. Copper (may use larger, incl. 3/8-in Aluminum): Each of Six Whiskers = 92-inches, Top-Bottom Tine Separation = 51-inches & Feedpoint = 5-inches.
