Dipole antenna other monopole) antennas on the basis of dipole antennas of which they are one half. German physicist Heinrich Hertz first demonstrated the existence of radio waves in 1887 using what we now know as a dipole antenna (with capacitative end-loading). On the other hand, Guglielmo Marconi empirically found that he could just ground the transmitter (or one side of a transmission line, if used) dispensing with one half of the antenna, thus realizing the "vertical" or monopole antenna. For the low frequencies Marconi employed to achieve long-distance communications, this form was more practical; when radio moved to higher frequencies (especially
Radio Marconi “Most InAVative Leisure & Entertainment Facility” category at the InAVation Awards 2013, for the interactive multimedia seatback system integrated into the Royal Opera House in Muscat. The company is known mainly for its surtitle and supertitle systems, as well as the electronic libretto, seat back titles, and libretto translation technology. It is also known for its wireless and touch screen technology. These devices are not computer-based, resulting in no moving parts, no sound, and no overheating. These products allow users to view video channels, download content, and participate in surveys, among other applications. Radio Marconi systems can reproduce any existing
