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....

Hi Dave, WB6LLO
Your Quadrifilar Helix will work very well as a feed for a dish and with a
minimum  spillower if the F/D ratio of  the dish is ranging from 0.3 to 0.35
See my article " Experimental Investigation on Quadrifilar Helix Antennas
for 2400 MHz" publisched in AMSAT-Journal May/June 2004
