The new $2,000,000 telescope will have a 140-ft. paraboloid antenna (second in size only to the 250-ft. antenna being constructed in England) which should allow it to pick up spatial wave lengths ...
There are lots of different antennas on the market. How do they pick up TV signals? And will I need to get a new one to get digital TV? —Ian ...
Hyperbolic paraboloid origami harnesses bistability to enable new applications Date: September 17, 2019 Source: Georgia Institute of Technology Summary: Researchers are looking the 'hypar' origami ...
He wrote software to simulate throws from hundreds of positions to determine the shape for the board, which ends up looking like a shallow elliptic paraboloid.
A single five-element Yagi antenna was used with each of the 49, 91 and 173 Mc./s. receivers, and a twelve-foot paraboloid reflector antenna was used with the 492 Mc./s. receiver.
The antenna reflector is an aluminium paraboloid, 10 feet in diameter with a focal length of 35.8 inches.
The cylindrical array consists of three paraboloid reflector antennas, each equipped with 96 feeds, while the dish array includes 16 six-meter diameter parabolic antennas.
Researchers at the Georgia Institute of Technology and the University of Tokyo are looking the 'hypar' origami for ways to leverage its structural properties.
