They (we called them the "Type W") were the mainstay of the FCC's HFDF
system from the 1970s to several years after I retired in the mid-1990s.
 Their function was directivity, not gain.  We took the military's
design and one of our engineers improved on it, and we usually
outperformed theirs on tests.   AFAIK all of the FCC's and the
military's are now gone, replaced by more sophisticated DF antennas.
