Not to belabor the subject, but I had an RF engineer friend who had 
access to some very sophisticated signal measuring equipment, and we 
did many actual signal receive comparisons on several 
satellites...with both antennas

Several leos and on AO40.  We used coax switching for an immediate 
comparison, and the quadrifilar was superior....

Easy and inexpensive to build...

See quadfilxxxxx on:


With detailed measurements for 2M, 435 and wx satellites....I scaled 
one for 2.4 gig feed on a 36" dish, and it worked very well, but not 
sure it was fully illuminated....

                    Disagree: I learn....

               Pulling for P3E...
