For sure.

I also can't believe that they're getting almost $70 for the very same loop 
antenna you can make for literally nothing (if you have the parts) or for 
well-under $20, if you have to buy them. I could see getting $30-$35 for it, tho. 
That would be reasonable. I dont' think $70 is reasonable for what it is.

I also have to laugh at one of thier pages, which claims that they *invented* 
this (loop) antenna. Hmmm... I think that the loop antenna was invented long 
before C.Crane ever existed.

Interesting. So... what's the benefit, then? Two coils on the same core are, 
effectively, one coil. (Or they are a transformer.) More technical tomfoolery 
to confuse the unwashed masses into shelling-out more for a product than it 
may be worth?

More than one! Browse the site, and you will see a number of products 
intended to help pull-in the weak ones.

Once IBUZ takes over... who knows? They could have a major run on them, or 
people will simply give-up and they won't sell any. Unless the offending hash is 
coming-in at close-to-a 90 degree angle, it's going to be very difficult to 
null it all out. At home, WFIF and WTOP's signals arrive on azimuths only a few 
degrees apart. Nulling is nigh impossible. Best I can do is bring WFIF's 
signal in above WTOP's, and that's no easy task.
