[Milsurplus] BC-620/659 Antenna Wire Hookup

[WA5CAB at cs.com]

Group,

I have some of these but they are a couple of miles away and I'm hoping 
someone here has one they can just walk a short distance to and answer my 
question.  On the rear face of the BC-620 and BC-659 cabinet is a box to which 
the antenna can be connected.  The original box is open backed and houses an 
insulated metal block with a long screw through it.  The nut on the end of 
the screw (at top of block) is a long one which is a nut for the W-128 antenna 
wire and also a socket into which the packset antenna can be screwed.  
There are several later closed boxes that have a UHF coaxial connector and some 
have impedance matching components inside.  What I need to know (and I'll 
write it down this time) is what is the size or diameter of the screw to which 
the W-128 would be attached (if using it to connect to the antenna mast 
base).  I need to make up a connecting wire for an SCR-610 to send to an MV 
collector and can't convince myself that I know what terminal size to put on 
the radio end.
