Mounted on brackets at the dish's focal point is a device called a feedhorn. This feedhorn is essentially the front-end of a waveguide that gathers the signals at or near the focal point and 'conducts' them to a low-noise block downconverter or LNB. bis high schoolA directional antenna or beam antenna is an antenna which radiates or receives greater radio wave power in specific directions. Directional antennas can radiate radio waves in beams, when greater concentration of radiation in a certain direction is desired, or in receiving antennas receive radio waves from one specific direction only. This can increase the power transmitted to receivers in that direction, or reduce interference from unwanted sources. This contrasts with omnidirectional … bis hier und noch weiter adel tawil lyrics

"WebA type of reflector antenna that is designed in a paraboloid structure by using the parabola properties is known as a parabolic reflector. In this antenna, the active element is present which focuses the main axis to reflect the radiated wave in a parallel direction to the main axis.
