Guys,

I have sitting on my desk a commercial bauln which
is a 1:1 design.

The "design" consists of about 6 turns of about
pencil diameter coax wound on a toroid.

I'm more used to designs with multiple windings or
bead baulns.

I'm interested in using this to feed my 402CD 40
meter beam (50 ohms at
the antenna feed)

Questions:

Is this a valid "bauln" design?

Does it really transform unbalanced to balanced?  
I'm convinced from past experience that best beam
performance occurs when the feed is truly
balanced.  

Is it just a shrinkage (because of the toriod
permitivity) the 12 turn coax design which guys
seem to have both success and failure with?

Has anybody used similar designs on their 402CD?
