There are many shipboard communication antenna problems where the number, type, location, or survivability of a given antenna in the system is a parameter which can be varied to determine the overall optimal system. This thesis investigates computer numerical models f or improving the time that an HF shipboard combat survivable antenna system can endure in a given environment. The future generation of ships will have low profile combat survivable antennas; an interim solution for present ships is the elimination of fragile HF antennas by exciting existing masts. The antenna is modeled as a mast with dimensions 24 x 3 x 3 meters. Several computer models of the driven antenna are modeled using the Numerical Electromagnetic Code (NEC). Input impedances and radiation patterns of the antenna are presented.
