PPN-1A: Eureka Beacon
The PPN-1A setup would generally be brought in during a parachute drop and setup on the ground. To select a channel, the serviceman was required to appropriately adjust the position of the two coils. Once properly linked up, the job was to guide the later aircraft to the drop zone.
The British were the first to develop Eureka beacons in WWII and the US forces later modified the British design for the American forces. The very first American Eureka Beacon put into use was the PPN-1, which was used by airborne pathfinders at Normandy. The PPN-1 was modified into the PPN-1A, which was later superceded by the PPN-2.
