It consists of seven 200x9.5 mm rods in heat-shrinking tubing. I have never finished and tested the device, I have not even wound a coil over the super-rod, but I can post you a photograph: http://www.flickr.com/photos/g7ahn/6044225537/ I bough a set of eight ferrite rods from an ebay shop in Lithuania (I cannot remember the details, but I believe it is run by a ham). 73 Costas SV1XV -- PGP key: 0x07F2AAD0 (available on keyservers)
