SUMMARY
  
     
          The number type and function of equipments installed as well as methods of installation and power supplies are, except for differences in the antenna system listed below, substantially identical with IXC vessels.  Reference should be made to Report 2G-9C-S67 for detailed information.  
          a.  Antennas are as follows:  
                  1.  One wire rope antenna on the starboard side running from the after part of the bridge structure to a point just forward of the maneuvering hatch.  The stern antenna support is a pipe, the trailing side of which has been carefully faired.  
                  2.  Two vertical stub antennae which are located on top of the bridge structure, one port and one starboard.  These are withdrawn from their housing manually and locked in place.  
                  3.  One vertical retractable type antenna hoisted by compressed air enters pressure hull aft of C.T.  The space requirements for hoisting mechanism and the well within the vessel are considered excessive when compared with USN whip antenna installations on submarines.
