Just now I had to solder an RG316 (BNC on the other end) onto those pads to help understand a problem Gwyn is trying to explain to me. So I feel your pain.
The U.FL was left off during the design (6+ years ago now) due to cost and the belief no one would ever want to use it. As Monty Python said, "Nobody expects the Spanish Inquisition!"
Thanks for all the answers... I will look into ordering the necessary parts then to move on... I also need to find a way to get a connection from the GPS antenna through the concrete to the basement, where the radio lab is - the existing cable tubes are full...
