What is "antennas"

Usage examples of "antennas".

Elint towers, odd-shaped antennas secured in cement, warning signs, and radomes that looked like giant Ping-Pong balls were erected.

A twelve-foot-long pod containing even more antennas and receivers was occasionally suspended from the right side of the aircraft.

Scores of antennas, like small blades, were attached to the fuselage, each dedicated to particular frequency bands.

Unlike the standard high-frequency communications, which were vulnerable to foreign direction-finding antennas, the moon-bounce signal was virtually undetectable because it used hard-to-intercept directional microwave signals.

Here, amid the frogs and snakes and antennas, Tordella sat out the remainder of the war.

In the blockhouses at the center of the massive antennas, intercept operators scanned the frequency spectrum hoping for a hit.

Soviet engineers and signals intelligence specialists erected acres of antennas to eavesdrop on American communications.

Giant rectangular antennas, like drive-in movie screens, were erected to intercept microwave signals.

Like a steel ark, it sat high above a sea of giant rhombic eavesdropping antennas planted in the tundra and pointing in every direction.

As the floe migrated through the Arctic Sea, like a ghost ship adrift and lost, the polar spies used advanced acoustical equipment to detect hostile subs, while special antennas and receivers eavesdropped on the other side.

The idea of Melody was to focus Elint antennas on Soviet ballistic missiles during their test flights and follow their trajectory.

The intercept antennas were able to pick up signals from Soviet high-powered radars well over the horizon as they bounced off the missiles.

Dozens of rhombic antennas, arranged in rosette patterns, were constructed to sweep in the Communist communications.

The listening post was set up in a secure room in the building, the operators hidden under the cover of communications specialists, and the antennas disguised as flagpoles.

The enormous antennas were dismantled and the intercept operators sent back to NSA a decade later, in 1977.
