feedhorn造句

• The feedhorn also selects the circular.
• The actual gain depends on many factors including surface finish, accuracy of shape, feedhorn matching.
• A similar feedhorn configuration is used to produce the up / down delta signal ( not shown ).
• Mounted on brackets at the dish's focal point is a device called a feedhorn or collector.
• The sum signal is created by a feedhorn structure positioned to maximize signal at the center of the antenna beam.
• Due to the shape of the dish, an LNB with an oval feedhorn is required to get full signal.
• For a high gain antenna, the feedhorn assembly is located facing the reflecting surface at or near the focal point.
• The received radar return was detected in a single or adjacent feedhorn which the radar receiver calculated a relative position in elevation.
• The 3-D functionality was possible through the use of a " vertically stacked beam " radiating feedhorn into the parabolic reflector.
• The 150 GHz pixels are corrugated-feedhorn-coupled TES polarimeters fabricated in monolithic arrays at the National Institute of Standards and Technology.
• Certain devices can also allow a feedhorn to accept both linear and circular, though these cause a slight insertion loss to all incoming signals.
• The feedhorn then sends the signals through a waveguide to a low-noise block converter ( LNB ) or low noise converter ( LNC ).
• Note that with large dishes, it would be possible for the feedhorn to be damaged, which is prevented by the focus light or heat effectively.
• Antenna waveguide in COSRO systems includes an RF received feedhorn structure that produces a left / right RF receive sample and an up / down RF receive sample.
• The original C-band satellite television systems used a low-noise amplifier ( LNA ) connected to the feedhorn at the focal point of the dish.
• The iLNB combines the feedhorn and electronics for reception and transmission in one unit, and is provided with two F connectors for receive and transmit connection to the IPmodem.
• This is called the low-noise blockconverter ( LNB ), and the unit consisting of the horn plus the converter is called the LNB with feedhorn ( LNBF ).
• In the UK, the term " twin-output LNB ", or simply " twin LNB ", is usually used for an LNB with a single feedhorn but two independent outputs.
• LNBs without a feedhorn built-in are usually provided with a ( C120 ) flange around the input waveguide mouth which is bolted to a matching flange around the output of the feedhorn or polarizer unit.
• LNBs without a feedhorn built-in are usually provided with a ( C120 ) flange around the input waveguide mouth which is bolted to a matching flange around the output of the feedhorn or polarizer unit.
