Simulation of slanted shipboard VHF antenna radiation pattern

Slanted shipboard VHF half-wavelength antenna simulations in NEC were presented in paper. The effects of antenna height above sea surface and slanted antenna elevation angle on radiation characteristics were studied. Change in the antenna height affected the number of lobes and thus redirected maximums and nulls along the elevation angle. The pattern envelope was not affected. Antenna slanting did not cause the slanting of its pattern.
