EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES.
The radar set consists of three major groups of equipment: a radar set group and two control indicator groups. The radar
set group contains the base pedestal, the receiver-transmitter group, azimuth antenna, azimuth antenna drive, elevation
antenna, and elevation antenna drive. The two control-indicator groups are identical. Each control-indicator group
consists of a control-indicator, pulse generator, and tubular frame. The radar set provides information used for air traffic
control, airport surveillance radar (asr) to a maximum range of 40 nautical miles and ground controlled approach (gca)
landing of aircraft. Range, azimuth, and elevation information relative to the aircraft's position Is displayed to direct the
aircraft along electronic cursors (elevation glidepath and azimuth course line) for a precision gca landing. A height-
finding capability is provided with a direct readout of the aircraft that is within a 30-degree sector of the gca flightpath.
The radar displays Include an Identification Friend or Foe (IFF) presentation capability (during asr) designed for use with
Interrogator Set AN/TPX-44.

LOCATION AND DESCRIPTION OF MAJOR COMPONENTS.
AZIMUTH ANTENNA
The azimuth antenna consists of an azimuth reflector, an azimuth waveguide radiation horn and polarizer assembly, and
an azimuth horn and polarizer support. The reflector Is constructed of a fiberglass exterior over a lightweight
honeycomb. The reflecting surface Is a laminate of woven metal cloth on the front side (concave side).
