Hi-VHF+UHF "VEE" Stick Dipole Hi-VHF+UHF "VEE" Stick Dipole (No Reflector) analyzed using 4nec2 after using nikiml's Python Optimization Scripts to determine the "best" Element Length and Forward Swept Angle to "best" cover BOTH Hi-VHF and UHF Bands. Hi-VHF Raw Gain = 2.1 to 2.5 dBi and SWR (300-ohms) = 3.0 to 3.3. UHF Raw Gain = 4.5 to 3.9 to 4.5 to 3.0 dBi and SWR (300-ohms) = 2.0 to 3.6 to 2.6. Date(s): 25 Jul 2014.
