The AN/GPN-20 is a dual-channel radar system with tower-mounted antenna and remote site operator controls. Its mission is to detect aircraft within 60 nautical miles of the radar site and to process and display information for air traffic controllers. The solid-state system is equipped with frequency diversity capability so that it may operate with both channels simultaneously or with either channel independently. This antenna was in use at Dover AFB until 2012 when it was replaced with newer, more precise equipment.


Staff Sgt. Wilfong, 436th Communications Squadron ground radar systems technician, stands in front of this Airport Surveillance Radar while it was in service at Dover AFB. Although it was used for over 30 years it efficiently and accurate tracked nearly 200 targets on a daily basis until it was retired.
