Propagation of Very-High-Frequency Radio Waves

Abstract

DURING the period autumn 1949 – spring 1950, a series of measurements of field-strength from a very-high-frequency airborne transmitter was made at the Royal Aircraft Establishment. The main purpose of the investigations was to examine the field-strengths obtained in varying weather conditions with one end of the propagation path at a height of 40,000 ft. above the earth (the other end being at a height of 90 ft.) and to compare them with the field-strengths calculated from conventional ray-theory for a smooth spherical earth for both ordinary and four-thirds earth radius. For this purpose the two frequencies 280.2 and 386.6 Mc./s. were chosen.
