Describes magneto-ionic theory and application of optimizing the orientation of a linearly-polarized antenna such as a half-wave dipole for short-range communication via the ionosphere near the equator. Compares ordinary and extraordinary waves for overall performance over a major part of the day when communication traffic is active; comments on susceptibility to atmospheric noise, amplitude and phase stability of received waves, and on ionospheric layers supporting these waves. Deals with orientation diversity through radio-teletype measurements, and assesses performance of various antenna systems for transmission and reception. Presents a simplified method of planning antenna configurations for tactical HF communication in Thailand. [TAIC]
