ASR-2
ASR-2 was operating in S-Band terminal area surveillance radar.
The reflector antenna with a dimension of 10 × 12 feet (3 × 3.7 m). The horn radiator is vertically polarized. The antenna provides a cosecant squared pattern at 10 000-foot contour into an angle 30° above the horizontal plane. The transmitter used the frequency tunable magnetron Type 5586.
In 1953, the ASR-2 was installed on some US-airports, e.g., in Seattle and Indianapolis.
