Inscription.  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.
