This is from an ebay auction. It is pretty rare and the auction had some good pics, so I copied them for our reference section.

 

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 The PPN-1 was modified into the PPN-1A, which was later superceded by the PPN-2.

 

In the below official US Army photo, the carrying bag is strapped to a trooper.

The following pictures come from the official War Department manuals on the use of the PPN-1A:
