[Premium-Rx] RACAL HF ACTIVE ANTENNA AE3001/A/C/LP2 PART NO. 580-000 RACAL ANTENNAS UK LTD

Hi, I have recently acquired one of these fine looking beasts, a black  
plastic blob with a lovely water shield/ground plane, and about 1M whip 
attached  to the top, the only thing is that it came with no paperwork or interface 
 necessary to power the aerial. Presumably, one sends the supply voltage up 
the  CO-AX aerial feed, like the interfaces popular with Wellbrook, Datong 
etc, and I  am sure that if I looked that I could find one of these, but the 
question is,  what is the voltage that needs to go up the CO-AX? Has anyone 
got any ideas, or  better yet, racal paperwork for it? Maybe its standard 
12V, if so, I might try  it with my JRC receiver which has a switched 12 volt 
supply which can be  switched in or out of the aerial feed, any help much 
appreciated, Dave.  MW1DUJ.
