dc.description.abstractThe purpose of this thesis was to compare the performance of three tactical high frequency (HF) antennas to be used as possible replacement for the antenna system of the Tactical Data Communications Central (TDCC) . The antennas were modeled using the Numerical Electromagnetics Code, Version 3 (NEC-3) , and the Eyring Low Profile and Buried Antenna Modeling Program (PAT7) for several different frequencies and ground conditions. The performance was evaluated by comparing gain at the desired takeoff angles, the voltage standing wave ratio (VSWR) of each antenna and its omni-directional capability. The buried antenna models, the ELPA-3 02 and horizontal dipole, were most effective when employed over poor ground conditions. The best performance under all conditions tested was demonstrated by the HT-20T. Each of these antennas have tactical advantages and disadvantages and can optimize communications under certain conditions. The selection of the best antenna is situation dependent. An experimental test of these models is recommended to verify the modeling results.en_US
