[Premium-Rx] HF 2000 - ACTIVE ANTENNA

[Ahmet G.]

Hello everyone,
I am looking for any information you may have available on an Active Antenna, Model " HF 2000 " .
I have the main unit ( Amplifier ) but missing the rest of the antenna kit.
It would be great to get the schematic of the unit including the bias circuit along with feedline voltage value.
I searched online but cannot find anything about this antenna.
It looks like it was built sometime in 1996 most probably in Germany ( from date codes and brands of components).
This is off topic, so please contact me directly.
Thank you
Ahmet Gundes
