Hi Trimble has been making GPS for a *long* time. Your antenna dates back a ways. You see them for $50 to $100 if you do some careful shopping. They have about 50 db of front end gain and need 12V for power. They are pretty broadband compared to a timing antenna with built in filtering. All of that makes them a challenge to use with something like a Res-T or a T-Bolt.
