"Our affordable and state-of-the-art backhaul radios can be equipped with four high gain
parabolic antennas of different sizes for shorter and longer distance applications.
The Italian authors discuss branching, capacity improvement, modulations and coding, countermeasures against imperfections in TX and RX chains, low noise amplifiers, local oscillators, analog-to-digital converters, power amplifiers, upconversion, linearization techniques, and
parabolic antennas. ([umlaut] Ringgold, Inc., Portland, OR)
However, an array of
parabolic antennas is also limited by the field observable by the individual telescopes.
Solar analysts at Sagamore Hill Radio Solar Observatory near Hanscom Air Force Base, Mass., monitor the sun's radio emissions with a radio telescope that uses three
parabolic antennas of 28 feet, 8 feet and 3 feet in diameter, along with fixed semi-bicone and tracking antennas.
In days gone by, the industry used
parabolic antennas, above right, which created a beam with strong sidelobes.
The wireless network uses
parabolic antennas to extend to a central location, from which additional antennas reach out to rural areas at the furthest ends of the county.
Many homes outside the cable area have
parabolic antennas to receive television transmissions from a satellite far out in space.
High throughput requirements, professional installation of equipment, and strong competition from
parabolic antennas, render the main FPA value propositions moot.
