Breakall, J K; Christman, A M

The Numerical Electromagnetics Code (NEC) was used to model a ''single-wire horizontal dipole antenna'' used with the FCDNA continuous-wave measurement system (CWMS). Line drawings and construction information were supplied to LLNL staff by FCDNA and EGG personnel, and NEC models were developed accordingly. Data were obtained from NEC describing all components of the electric and magnetic fields at nine different field-strength measurement points, as well as the input impedance at the antenna feed-point. Thirteen frequencies were used in the model, ranging all the way from 10 kHz to 100 MHz. In addition, the antenna was examined in two configurations, with and without a coaxial transmission line which extended from the feed-point balun to ground level. 16 figs., 46 tabs.
