Ferrite Rod at HF

[Geaney]

Very topical as I'm half way through building the active ferrite loop antenna project from EPE (Sept 2000). I've got nine rods in the aerial setup. I've still to build the active circuitry - hope to get that done in a few weeks time when on hols. This project is specifically for MW reception - hopefully it will improve things in terms of MW reception in my neck of the woods.
My initial observation is nine ferrite rods taped together are heavy!

Cheers, John
