I'm a little lost regarding my "claim for gain" but I remember when I had the 3/4 wave radials on the Imax it seemed more broad banded.

What Nav2010 is saying about the base of the A99 is, if you could drill a hole through the radial mounting hub and continued into the antenna until you just met the coax shield inside the top of the A99 mounting tube and just below the matching network, then screwed a brass bolt through that hole all the way to contacting the coax shield inside - you would have eliminated about 24" of travel for the radial current which otherwise has to go back down from the match, inside the tube along the shield of the 12" piece of coax, to the bottom where the SO-239 is, then back up the outside 12" of the A99 mounting tube before it gets to the radials hub.
