LF: Ferrite rod array

["Peter W. Schnoor" <pwsch@nephro.uni-kiel.de>]

Hello Group,

I´m planning to combine the output of 
8 ferrite rods for comparision to my 
coax loop. Each rod has it´s own coil.
How should I arrange this array for
highest performance? One above the other? 
Next to each other?  On a straight line? 
Filling a volume?
Some years ago I built a "monster" ferrite 
rod by glueing 5x18cm rods together. It was 
much better than bundling them. Of course it 
was too fragile to handle and had only one 
coil. I don´t know how to simulate a ferrite 
rod with NEC.
Any ideas?
