This most frequent satellite antenna type is so-called because it is in the shape of a parabola, which has the purpose of focusing the received signal into one focal point located out in front of the dish.
An antenna having a main reflector surface that is a paraboloid or is shaped like a paraboloid. It has the property of reflecting parallel incoming signals to a single focal point.
An antenna in the shape of a parabola used to receive satellite transmissions. Generally referred to as a "dish". The parabolic dish is a reflector which focuses the satellite signal on the LNB, making the signal stronger. Most parabolic antenna dishes are of the "offset" type, with the LNB asymmetrically positioned. This prevents snow accumulating on the dish and reducing the signal.
Satellite TV antenna that is shaped like a parabola. Focuses weak microwave signal hitting the surface of the dish into a single focal point in front of the dish. It is at this point that the feed horn is usually located.
A directional antenna made up of a dipole driven element mounted in front of a parabolic-shaped reflector. The reflector may be either a solid metal “dish” or a dish-shaped screen made of metallic rods or mesh.
The most frequently found satellite TV antenna, it takes its name from the shape of the dish described mathematically as a parabola. The function of the parabolic shape is to focus the weak microwave signal hitting the surface of the dish into a single focal point in front of the dish. It is at this point that the feedhorn is usually located.
An antenna type that radiates a very narrow beam in a specific direction. Parabolic antennas offer the highest gain for long-range point-to-point situations.
The common shape of satellite antennas, described mathematically as a parabola. The parabolic shape focuses a weak microwave signal hitting the surface of the dish into a single focal point in front of the dish.
An antenna consisting of a parabolic reflector and a radiating or receiving element at or near its focus. Parabolic antennas are very directive and includes a preliminary source and a parabolic reflector to focus the energy.
An assembly consisting of a feed firing or receiving from a parabolic reflector.
An antenna employing a reflector in the form of a paraboloid. Common in weather radar, such an antenna produces collimated radiation from a feed at the focus, providing high gain and narrow beamwidth.
The parabolic antenna is a high-gain reflector antenna used for radio, television and data communications, and also for radiolocation (RADAR), on the UHF and SHF parts of the electromagnetic spectrum. The relatively short wavelength of electromagnetic (radio) energy at these frequencies allows reasonably sized reflectors to exhibit the very desirable highly directional response for both receiving and transmitting.
