Re: Ferrite antenna design in older portable radios

I've tried both ways of winding. If I remember correctly, I get better signal pickup with a winding that is the full length of the ferrite.
 
That said, I'd be curious to know the purity differences of the figure-8 pattern when the coil is short versus full length. Which is the better nuller?
