RMMYCDF9–. English: Drawing of an early demonstration Lecher line apparatus, from a 1902 catalog of scientific equipment. It is very similar to the first Lecher line built by Austrian physicist Ernst Lecher in 1888. A Lecher line is a pair of parallel wires or rods that were used to measure the wavelength of radio waves. In this example, the radio waves are generated by the Hertzian spark-gap oacillator (right) and sent down the Lecher line, the pair of parallel wires to the left. The Lecher line forms a length of balanced transmission line, along which the waves travel at the speed of light. At the le
