abstract: An umbrella antenna is a top-loaded electrically lengthened monopole antenna, consisting in most cases of a mast fed at the ground end, to which six or more wires are connected at the top, sloping downwards. The outer end of each wire is terminated by an insulator, usually placed at about one third the total height to isolate the lower support-wire or rope which is anchored to the ground.
