Hi-VHF Flat-Swept SBGH H-POL OMNI-PLUS Hi-VHF Flat-Swept SBGH (Single Bay Grey Hoverman) Horizontally-Polarized OMNI-PLUS Antenna analyzed using 4nec2 after determining BEST Dimensions using nikiml's Python Optimization Scripts. Min Gain = 4.5 dBi, Max Gain = 7.5 dBi, SWR (300-ohms) under 2.4. This H-Pol. Antenna provides OMNI+PLUS Azimuthal Pattern (Greater than 0 dBd = 2.15 dBi Gain in every direction), with a MINIMUM Gain of 4.5 dBi or MORE on ALL Azimuths. Date(s): 26 Jun 2016.
