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
recently picked up a Trimble 22020 L1/L2 antenna for a pretty good
price. It is in near perfect physical condition including the ground
plane. I Googled around a bit for technical specifications and so far
have found nothing very useful. Is there a source out there I am just
missing? I did
