BTW, some time ago I made a "super rod" which I intented to use
for NAVTEX on 518 kHz, as the electrical noise at my location
is very high. 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:

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).
