Antenna, Rebecca, AT-2/APN-2 Aerial Refueling thus corresponding BMEP with BHPThis WWII era "Rebecca" antenna is a AT 2 APN 2, but a version that has the brown (resin or masonite) stabilizing 'wings' between the mast and the blades. Two were typically mounted on each side of the aircraft forward of the wing, receiving navigational signals from the "Eureka" transmitting station and indicating those signals to the crewman on a BC 929 A receiver (not included). See photo of a similar antenna mounted to the fuselage of a B 24
