Antenna (radio) the focal point of parabolic reflectors for both transmitting and receiving. He published his work in "Annalen der Physik und Chemie" (vol. 36, 1889). The words "antenna" and "aerial" are used interchangeably. Occasionally the term "aerial" is used to mean a wire antenna. The origin of the word "antenna" relative to wireless apparatus is attributed to Italian radio pioneer Guglielmo Marconi. In the summer of 1895, Marconi began testing his wireless system outdoors on his father's estate near Bologna and soon began to experiment with long wire "aerials" suspended from a pole. In Italian a tent pole is known as
Guglielmo Marconi up on the ideas of physicists who were experimenting with radio waves. He developed devices, such as portable transmitters and receiver systems, that could work over long distances, turning what was essentially a laboratory experiment into a useful communication system. Marconi came up with a functional system with many components: In the summer of 1895, Marconi moved his experiments outdoors on his father's estate in Bologna. He tried different arrangements and shapes of antenna but even with improvements he was able to transmit signals only up to one half mile, a distance Oliver Lodge had predicted in 1894 as the
