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

Hi Dave

I wondered where that one went, I quite sulked to have missed it at the  
time:-)

Some versions take the supply up the coax, some have a separate power feed, 
 all require +31 volts DC.
It's a fairly standard active whip circuit, FET input and bipolar output,  
in this case though the former is a 2N6660 medium power MOSFET that Racal  
insisted had to be the Siliconix part.

About ten years ago I scanned the manual for these but looking at that  
again now I can see the limitations of the scanner I was using, probably of  
the bloke doing the scanning too:-), and am not best impressed with my  
efforts, so if you can bear with me I'll do it again today and let you  have a 
better copy later.

Regards

Nigel

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.
