I've found *one* reference on google to the Compaq WL110's interface:

Apparently this author says the interface is a SMA-RT (can anyone verify?) I popped the cap off on the end of the card and it indeed is a little round sucker that looks as if it would interface with my Raylink pigtail, but isn't quite right.

Searching cable websites, I've found a lot of references to a right-angle SMA, which they occasionally refer to as a RT, but would have to believe this is a different critter.

I see Nokia apparently has an SMA-RT - wonder if this would work: http://www.gwdata.com/cablesconnectors.htm

Sidenote: I should have known better, but still, nix calling someone like Microwarehouse / Datacomwarehouse (warehouse.com) and asking for the pigtail for this card. I got a lecture (must be preprogrammed in their script) that part 15 cards never support "pigtails" because that'd allow you to use nonauthorized antennas. Oh, they'll sell you the official $110 compaq "booster antenna."
