UHF + Hi-VHF V-Hawk by Ronbo Hi-VHF + UHF V-Hawk Antenna analyzed using 4nec2.  Dimensions as per 4nec2 Files posted by user [Ronbo].  His Assembly Instructions & Photos are at bottom of this Webpage. Note that V-Hawk wires are CONNECTED at the Top and Bottom, whereas Stealth-Hawk has a GAP, hence it is NOT formally derived from the Chireix. Three versions were analyzed, with 30, 45 and 60-deg Forward Swept Angles: ==================================== a) UHF + Hi-VHF V-Hawk - 30-deg Angle: UHF Raw Gain = 10.8 to 14.3 to 10.7 dBi and SWR (300-ohms) under 1.8, with Primary Lobe Forward and Secondary Lobes 110 to 120-deg away. Hi-VHF Raw Gain = 5.2 to 6.2 dBi, F/B & F/R = 0.3 to 0.4 dB and SWR (300-ohms) under 2.3 with Bi-Directional, Quasi-Omni Coverage. ==================================== b) UHF + Hi-VHF V-Hawk - 45-deg Angle: UHF Raw Gain = 9.6 to 14.3 to 12.2 dBi and SWR (300-ohms) Under 1.8, with Primary Lobe Forward and Secondary Lobes about 90-deg away. Hi-VHF Raw Gain = 4.6 to 5.3 dBi and F/B & F/R = 0.5 to 0.7 dB and SWR (300-ohms) under 2.3 with Bi-Directional, Quasi-Omni Coverage. ==================================== c) UHF + Hi-VHF V-Hawk - 60-deg Angle: UHF Raw Gain = 7.6 to 12.3 to 10.3 dBi and SWR (300-ohms) under 2.3, with Very Wide Beamwidth Forward and minimal Gain to Rear. Hi-VHF Raw Gain = 4.0 to 4.2 dBi, F/B & F/R Ratio = 0.3 to 0.7 dB and SWR (300-ohms) under 4.4 is Excessive with Quasi-Omni Coverage Pattern. Date(s): 4 Aug 2015.
