[BC] dual ferrite AM antenna

[Rob Atkinson]

thanks willie; i'll look at those antenna plans.   c. crane does say in the 
faq for the unit that two can be used spread apart for even better 
reception, but that's a 200 buck antenna which is a little too serious for 
me.  in fact, $99 is too serious.  btw, it turns out it's two coils on a 
single ferrite stick; not two separated loopsticks as I had previously 
thought.  it is kind of interesting to me that there is a general consumer 
product and market for fringe AM reception.   I wonder how many of these 
they sell.

I would imagine it's performance not much different than the tuned-loop... 
It
looks like the ferrite core/coils are housed in that larger black unit. If
the loopsticks were seperate, and could be phased/tuned independently, I 
would
imagine it would be far more effective at eliminating interference.

I don't know about eliminating fade, either. The only way to minimize that 
is
with Diversity, and at MW freq's, you'd need to put those antennas fairly 
far
apart.

The only instant advantage I see to this over their tuned-loop, is that this
looks like it's meant to be mounted outdoors. That, alone, could be a
significant improvement for marginal situations with lots of 
internally-induced RFI &
shielding.

I have easy do-it-yourself plans on my WEBsite, to make a nice tuned loop
antenna that works amazingly well.
