Does anybody know which antenna I am talking about?

It fits inside a 8" x 1.25" piece of pvc pipe and half of the pc board
is the antenna. It uses a U310 fet and some bipolar following that.
Maybe a 2N5809. Stick it on a non-magnetic pole and the 12v supply is
in the house. I am looking for the link to it. A friend and I are
building them, but I left the documentation at my other QTH. If you
have any experience with it then I would like to hear what you think.

I'm also building the AMRAD active antenna, but the high dollar fets
aren't here yet.

Could be the North country active antenna.

Not sure. I don't see the schematic on the north country site. I'm
sure thsere are a bunch of good designs out there. I'll post a link
to it when I get back to NY next week. My friend said he was very
happy with the performance and will compare to a couple of other
antennas he has. Maybe I can coax him into writing something down and
publish.

Crystalonics fets got here for the Amrad. The wife thought they were
LEDs so when I asked for fets she told me they didn't come.

The following link shows a FET amplifier followed by a bipolar
transistor coax line driver. Different FET and transistor than you asked
for though. See page two for the schematic.
