OPTIMUM ANTENNA ARRANGEMENT FOR A VLF VERTICAL-INCIDENCE IONOSPHERIC SOUNDING SYSTEM,
Abstract
A horizontal dipole near the earth is a useful transmitting antenna for vertical-incidence ionospheric sounding at VLF, but interference from a component of the ground wave presents a problem. Equations are derived to show that an angle of plus or minus 16 degrees off the axis of the transmitting dipole is the optimum position for placement of the receiving antennas to avoid this interfering signal.
