Antenna, Loop Unit. Mosquito Bomber
This is a WWII-era MN-20A 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. These aerials were also fitted to RAF Aircraft built under licence in America and Canada. It is shown fitted to a Canadian Mosquito
The MN-20 range of aerials were also retrofitted on various P-40 Warhawk and P-51 Mustang models in the China/Burma/India theater.
