A Monopole antenna is half the size of a dipole antenna. It was first discovered by a radio expert Guglielmo Marconi in the year 1895. He patented this antenna after one year in 1896. This radio expert was successful in performing various historical experiments in the field of radio communication.
When radio communications come into play, the antenna plays a more than crucial role. For amateur radio communications, the UHF antenna directive is the best antenna. Visit smelettronica.com for the best antennas.
