[Elecraft] loops

[Merlarts at aol.com]

I love loops.  They're quiet, have lots of capture area, wide  bandwidth, and 
when big enough, don't have the big horizontal spikes that  collinears or 
other horizontal wire antennas have.  
 
But here's my question:  Does anybody know whether the stup on Radio  Works's 
superloop is open or closed?  Methinks it's probably open, but I  bet 
somebody out there knows for sure.
