Shipment for SK included spares, with tubes for 400 hours, and a separate generator if the ship's power is DC. SK was not air transportable. SK had 10 components weighing approximately 5,000 lb (2,300 kg). The heaviest unit, at 2,400 lb (1,100 kg), was the antenna assembly. The antenna measured 15 ft (4.6 m) x 16 ft 9 in (5.11 m).
Most of today's radar detectors detect signals across a variety of wavelength bands: usually X, K, and K a. In Europe the K u band is common as well. The past success of radar detectors was based on the fact that radio-wave beams can not be narrow-enough, so the detector usually senses stray and scattered radiation, giving the driver time to ...
A radar detector detector (RDD) is a device used by police or law enforcement in areas where radar detectors are declared illegal. Radar detectors are built around a superheterodyne receiver, which has a local oscillator that radiates slightly. It is therefore possible to build a radar-detector detector, which detects such emissions (usually ...
FuMO 1 - Calis A: Its 6.2 x 2.5m antenna consisted of 2 rows of eight full wave vertical dipoles. Its wavelength was 82 cm and its range depended on the height it was installed above sea level, but typically was about 15–20 km. [ 7 ] Given the frequency low angle reflections from the surface, also known a clutter would have been an issue.
This is a list of World War II electronic warfare equipment and code words and tactics derived directly from the use of electronic equipment. This list includes many examples of radar, radar jammers, and radar detectors, often used by night fighters; also beam-guidance systems and radio beacons.
System accuracy is typically better than a microwave surveillance radar, and is a function of the deployment geometry, the inherent timing accuracy of the central site, the bandwidth of the pulse being detected and the signal-to-noise ratio. Wider separations of the side sites from the central site provide better accuracies – but at the ...
Metox was the German answer to the British radar. Metox sets received the transmitted pulses from the ASV and rendered them as audible beeps. It enjoyed the usual advantage of radar detectors over radar in that the signal is direct and only had to travel one way whereas the radar has to detect the very weak reflection from the submarine.

The AI Mk.IV radar was the first operational aircraft interception (AI) radar.It was used experimentally in April 1940, and entered widespread service in early 1941. These systems used a set of four receiver antennas that were arranged so they were most sensitive in different directions; two were sensitive above or below the aircraft, and the other two to the left and right.
