Mag loop aerial for the Den

[pwdrive]

I Googled Wellbrook loop and ferrite the other day, not a lot turned up, as Trev says it might be something to do with coupling the loop to the amplifier, I've seen ferrite used for that with single turn tuned loops, just a toroid slipped over the loop at a low impedance point (opposite the gap) with some turns wound around the toroid for the take off.
