The antenna schematics and photos are on TVB's site as Dan  suggested....
These are much better quality than those in the HP manual so well worth  
getting both.

Paul, to  get these to work, you will need  the loop antenna.  This has,  
in the early versions at least, a  Nuvistor amplifier in it with a  
crystal filter built in to it.  I  think there was a later  version that 
had transistors.  I have seen  the schematic  somewhere, have you tried 
TvB's site?

Hi Dan and Paul

The  ops and service manual is available from the Agilent  site........


Although not the best pdf manual ever it does contain the  schematics,  
including both antennas, and should be  usable.
