Excellent! I'm sure glad I had the bravery to ask the question
about that to the theoreticians out there (I was almost too chicken,
since the time I've been on this list (couple months), the talk has been
that any coil of significant size, expected to perform to any real degree,
*had to have* a RSG, and I wasn't looking particularly forward to making
Just a linear array, with no airflow arrangement?
I was thinking about trying to build such a gap on the interior
of a large diameter pipe, ala RQ, for possible application of a large
pancake fan. But, if you're getting good results without, I think I'm
just gonna try a straight one.
