Wile E. Coyote

Found out when I was looking for one that the AS-4333/V specified for the PLGR is actually the AeroAntenna Technology AT575-29. If you go to Ebay and key in "AT575" in the search box, you regularly come up with a bunch for sale with and without the magnetic base for under $20 bucks (there are two-three right now as a matter of fact), but the trick of course is to find the weird-ass Rockwell PLGR antenna cable to hook it up to the PLGR. I fluked out on the one I found about a year ago and haven't come across one since, though if you feel like opening your wallet you can get the cables through Rockwell-Collins still -- or better still get them from where RWC gets them...which is 3D Marketing...at between $75-$85 depending on whether you want the 5 meter or 10 meter one. Their price on the antenna hockey-puck itself is...heart stopping...so hit up Ebay.
