Is anyone on the list a collector or expert on the MK II Rebecca/Eureka beacon system? [AN/APN-2 & AN/PPN-2] It was used for para drops in Europe and elsewhere. It apparently continued in use through the mid 50s in Canada. Here is a link to a site: http://www.qsl.net/pe1ngz/airforce/airforce-raf/raf-eureka-rebecca.html#Rebecca Mk II I have some questions about the antennas for the system. Thanks, -John
