The SCR-270 radar antenna was part of a mobile radar system operating at 104MHz that could detect and track aircraft at 125 miles. This antenna is a 1943 production version of the radar that tracked the incoming Japanese raid on Oahu, Hawaii on 7 December 1941. It was later used by the University of Saskatchewan in Saskatoon, Canada, to study the Aurora Borealis at frequencies of 58 and 105MHz, collecting some of the very first radar echoes from the Northern Lights.
