Radiation resistance of thin antennas of arbitrary elevation and configuration over perfectly conducting ground

Dipole segmentation is used to estimate the radiation resistance of thin antennas of arbitrary elevation and configuration over a perfectly conducting ground plane. Utility of the method for estimating the radiation resistance of VLF/LF trailing wire antennas from aircraft depends upon the extent to which the current distribution deviates from a sinusoid. That deviation is due in part to finite wire thickness as well as the finite conductivity of both wire and ground. The influence of those effects requires further study.
