    RELEASED FOR THE EXCLUSIVE USE BY: AIRCRAFT ELECTRONICS ASSOCIATION KRA 405 2.4.3 ANTENNAS 2.4.3.A Approved Antennas The KRA 405 Radar Altimeter System requires two antennas for a single system in- stallation. Since the system is CW, one antenna is used to transmit the signal and the other is used to receive the reflected signal.
  • Page 19 RELEASED FOR THE EXCLUSIVE USE BY: AIRCRAFT ELECTRONICS ASSOCIATION KRA 405 2.4.3.B.4 ANTENNAS MAY BE MOUNTED IN LINE OR SIDE-BY-SIDE, the former be- ing the best choice of the two. When using side-by-side installations, the an- tennas should be mounted on a flat surface of the aircraft. The angle between the antenna centerlines should be less than 6 deg.
