Antenna, Loop Unit, MN-20E for MN-26 & RA-10 Radio Receivers, AN/ARN-11 Korean War From our researchThis is a WWII era MN 20E rotatable loop antenna, combining directional finding and general radio signal receiving, for MN 26 and RA 10 Radio Receivers as used in bomber and transport aircraft of the US Army Air Force and US Navy. Later, the system was designated AN ARN 11. The loop was rotated by a control panel (such as the MN 28, not included) at the navigators station, which was connected to the antenna base with flexible shaft cables. The MN 20E
