Topband: Split shield loop rx aerial question. . .

[N0OCT at sbcglobal.net]

I have a question about the split shield receiving loop antenna.  
Typical designs I have seen have been make with coax.  Is anything 
about the antenna improved if more than one conductor is contained 
within the shield, and is a 'continuous conductor', rather than 
just having the ends shorted at the feed point?  I'm asking here 
because I'd like to hear from someone with real experience with it,
rather than theory.  Thanks!
