[ARC5] AN73 Antenna Coax Connector

[Mike Hanz]

Steve advises me that it has a 1"-26 thread on the connector.  That's 
the same as an SCR-522 coax connector, though the 7 foot rod antenna was 
not meant as a VHF antenna.  The aircraft was, however, used by the 
British, which probably explains the choice of fuselage antenna interface.
