AN/AS-133/APX Aircraft Antenna Assembly – “DO NOT PAINT” Military IFF Antenna

Original U.S. military AN/AS-133/APX aircraft antenna assembly, identified by the manufacturer’s data plate marked AS-133/APX and N.O.A.S. 51-064. This aircraft-mounted antenna was designed for APX Identification Friend or Foe (IFF) systems used on post-WWII and early Cold War military aircraft. The antenna retains its distinctive yellow “DO NOT PAINT” warning finish, cast mounting flange, and threaded coaxial connection. Shows honest service wear while remaining an excellent original example of early military avionics equipment. A desirable display piece for collectors of military aviation, radar, IFF systems, and aircraft communications equipment.
