...Frederick August Kolster, who has contributed as much to radio as any man now alive, has invented yet another radio device, a machine for shooting a radio beam at whatever point on earth he pleases. His previous inventions have been the invaluable radio compass, the radio fog signal system, the mobile radio beacon to protect ships in fog, the decremeter which measures wave lengths and dampens radio oscillations, the Kolster radio receiving set. He created the Bureau of Standard's radio section and is its chief. He is chief research engineer of the Federal Telegraph Co. and its allied...
News of Dr. Kolster's latest invention developed last week as work went on to set up an experimental station near his Palo Alto, Cal., home...
...transmitter consists of a parabolic reflector, at whose butt end is an enormous vacuum tube. The tube sets like the heating element of the common portable electric heaters. The heater's reflector is basin-like. Dr. Kolster's radio reflector is so vast (20 feet across the rim) that it resembles a funnel...
...supposition, such a straight-going beam would be tangential to the earth's curvature and so never reach distant earth points where radio stations may be. By scientific theory, two possibilities exist. The Kolster beam may be skillfully aimed at the Heaviside Layer† and be reflected down to its receiving station, just as a pool player bounces a ball from cushion to pocket. The other possibility is that gravity will drag the beam to the proper curve of the earth...
