Abstract

Aboard his yacht Elettra, Guglielmo Marconi first used frequencies of about 500 MHz over long paths up to 250 km ¿ almost nine times the optical distance. He was well aware that his observations did not square with accepted theory of the day. In fact, he noted: ¿The speculations that may arise from such results concern the entire theory of radio transmission over distances greater than the optical one.¿
