Dual Stacked 5 Wavelengths per leg. 17.9 dBi
Screen shots of geometry, gain graph and plot, SWR and the 4NEC2 code used to produce the model.
Very flat Gain across the entire UHF band and excellent SWR.
Some screen shots imply this is a 4 wavelength per leg design. This is 5 WL / leg. I scaled this up from a smaller design and failed to catch the file naming convention.

Reason: Corrrected description to 5 wavelength per leg, not 4
