The very new satellite antenna, approved by Satellite Radio has been
specially designed to receive signals from three satellites and other network of
ground-based repeater transmitter. Satellite antennas are exceptionally
sensitive and delicately specified to assist reception of satellite signals
under a variety of conditions across the cou...
Antennas are electronic devices used to transmit and receive radio signals. Antenna is an arrangement of aerial electrical conductors. Heinrich hertz discovered antennas in 1888. For the first time he used the antennas to prove the existence of electromagnetic waves. The antennas convert radio frequency electrical current into an electromagnetic wa...

The omni directional antenna is an antenna system that radiates power uniformly in all directions. The only 3 dimensional omni directional antenna is the isotropic antenna, a hypothetical construct derived from actual antenna radiation patterns and used as a suggestion for specifying antenna gain and radio system effective radiated power. Practical...
