Dye-2 Distant Early Warning line radar a.k.a. Icecap 1; closed 1989.
Primary longrange searchradar for the 4 DEWLine sites in Greenland was the AN/FPS-30 made by Bendix, known as "Sentinel" radar.
Planned as replacement for all AN/FPS-19 DEW-Line radars, the AN/FPS-30 was installed in 1961 only at the 4 Greenland "DYE" radar stations.
It operated in 570 - 630 MHz range with a peak power of 150 kW and average power of 3 kW.
The AN/FPS-30 radar's pulse-repetition frequency was 500 pulses/sec. and the antenna aperture was 45 ft. x 25 ft.
Transmitter output tube was a Klyston with 62-dB gain (the Klystron poweramp was later adapted for the Raytheon-built AN/FPS-28 frequency-diversity air-defense search radar).
