Comdel HDR101A Preamp Help

[KB3DKS]

  I have this Comdel HDR101A RF preamp module that I would like to mate up with a loop antenna.
Is anyone familiar with these?

Comdel no longer offers any support info and the only data found so far is a patent # 4207572 that details the design of a D.F. assembly application using these amps.

  Some time ago I managed to figure out the connections and with a 5 volt supply was able to see 10 db gain with a 6 mhz input matched to 50 ohms both ends.
  Don't have the gear to duplicate the tests now but would like to build up a small loop to use at home and null out the household noises which otherwise make any other inside antenna useless. Just not possible to hook an outside wire. Not my place.

 Any further info would be appreciated.
