[ARC5] AN73 Antenna Coax Connector

[Mike Hanz]

I notice that T.O. 01-60HB-2 for the A-36-A refers to the mast only as 
an N.A.A. antenna (North American Aviation), which is consistent with 
speculation that it was made especially for the initial 500 aircraft 
delivery of the A-36 for USAAC use in the European Theater.  A note on 
the drawing says, "The antenna mast is used with the SCR-522 radio set 
and for that reason is insulated completely from the fuselage.  Care 
should be taken to prevent accumulation of conductive debris around its 
base."  Only a closeup photo of the inner conductor interface will 
confirm the theory, but all the clues point to it.

73,
Mike
