[ARC5] [Milsurplus] Unknown Antenna

[scottjohnson1]

Maybe the VHF command sets?  Or perhaps the ARC-4?

Speaking of "UHF" connectors, anyone know which was the first (US?) equipment that used an SO-239 "UHF" type connector?

Thanks to all who answered my enquiry on the unknown antenna. It looks like 
this antenna's base could be used with many different rod antennas of different 
lengths to match frequency range, and possibly was.  However, this one has 
the nomenclature embossed under its base with very shallow lettering that is 
difficult to read in ordinary light.  Upon closer examination with a 
magnifying glass and angled light it reads AS-32  APX-1.  Note 32, not 
82 as previously mentioned.
 
I could not find much info on the APX-1, except for this photo:

  That's the third antenna that looked like the AT-5 and 
  AT-8, resonant somewhere around 170 MHz I believe, for a JAN-nomenclatured 
  slightly modified version of tbe SCR-595-A Mark III IFF set.

    I now see in my own enlarged photo what I couldn't see on the real 
    thing.  On the bottom flange of the base its says AS-82 / APX-1. So I 
    guess its for an IFF transponder.  Will have to look up that.

      I would say drone control, or early IFF, the base looks 
      like a typical WWII whip base that was used for those purposes.  
      Maybe Television transmitter for RAZON/ AZON.

      Does anyone recognize this antenna and know what it was 
      used for?
      
      
      
      There are no markings on any part of this 
      antenna.  The yellow mast is 15-1/2 inches long and screws onto a 
      1/4-28 stud in the base.
      
      The base has a standard UHF 
      connector.
      
      
      
      Maybe target drone or something like that?  Mike
