AN/MPN-1
was used to assist the process of directing aircraft over a predetermined glide path for safe approach to an aerodrome runway under conditions approaching zero visibility. A V-8 truck contains the system's two PE-127 power units (rated output of each 7.5 KW), one air conditioner unit, and equipment spare parts. An additional diesel generator was usually mounted on a bomb trailer and towed behind the radar trailer. The V-2 trailer contains the system's radar and communications sets. The radar provides range and azimuth information on aircraft within a radius of 30 miles (48 km) with an operational ceiling of 4,000 feet (1,200 m). High Frequency (HF) and Very High Frequency (VHF) communications were provided by the SCR-274 transmitter, and BC-342 receivers. Ultra High Frequency (UHF) communications were added later via tactical radios normally jeep mounted for use by forward air controllers.
