Hello,

The SRT AA300 active antenna is a quite common item in Europe.

It is of early 70-'s vintage, and was designed as a general purpose active antenna. However, the most common application was for shipboard use.

I have the AA300 technical manual and the schematic for the power supply unit. If you want, I can scan and email it.
The schematic for the antenna unit was not published in the
technical manual due to a patent issue, but the unit consists basically of a FET high-impedance buffer and a bipolar transistor cable driver. 

I will try to find the complete schematic.

73/
