Yes. Free Flight uses part number 9-1203-115-00 in their catalog and installation manual for the radar altimeter antenna used in their RA3500, RA4000, and RA4500 systems. When you inspect these antennas, they are packaged in a Sensor Systems box with the 9-1203-115-00 part number label on the outside of the box. When you open the Sensor Systems box, you can immediately see that it is actually the Sensor Systems S67-2002 antenna. The antenna has the S67-2002 part number on its dataplate.
