[Milsurplus] Phantom Antenna Component Values

[Mike Hanz]

Yeh, the 7777 is the same unit as the Signal Corps A-61, Robert.  Jack 
Antonio was referring to the A-55, which values I couldn't confirm in my 
cursory search of the basement.  I conjectured it might be the same as 
its Navy GF cousin - 20 ohms and 100 pF - since both were designed by 
ARC in the thirties and have similar needs, but it was only speculation.
73,
Mike
