The Equi-Signal Zone Radio Beacon and Air Navigation

Abstract

THE application of directional wireless methods to assist aerial and marine navigation has been progressing steadily during the past few years. After passing a period of uncertainty as to its accuracy and reliability, the wireless directionfinder has established itself as a very useful aid to marine navigation. Many hundred ships of all nationalities are now fitted with direction-finders, and a large number of fixed beacon transmitting stations are now in operation in various parts of the world for the specific use of such direction-finding installations.
