Umbrella antenna

A screen antenna is a transmitting antenna, which consists of an insulated against ground radiating transmitting mast, are stretched from the tip of wires either to other masts, which can also be grounded or to anchor foundations, these wires electrically connected to the mast connected and isolated to the anchor points are suspended. These wires provide electrical extension of the signpost by means of their capacity to ground. Umbrella antennas are built primarily for long and long wave, since it is often not possible for these frequencies to build a transmission tower with the necessary height.
