(I think you mean "below 2:1.")

Yes, as a matter of fact, Frank Witt, AI1H, wrote a nice QST article on
this about five years ago. I think it was published in the summer or
fall of 1993, just after I left HQ. It was one of the last articles I
edited for QST.
Dave, W6NL, has also tried this, and it works for him.
