ANTENNA
Boeing P/N S220T114-101
The DM N56-1, designed for the Boeing 757 and 767 aircraft, provides a concept that can be incorporated in many aircraft design to provide integral VHF navigation systems performance.
The DM N56-1 free standing, balanced-loop array is mounted on the tip of a vertical stabilizer and covered with a structural fiberglass housing forming the fin tip. This approach provides a lightweight antenna system utilizing available space for maximum efficiency.
The electrical design provides a two receiver operation with performance assured for CAT.III conditions. The omnidirectional radiation patterns in the horizontal plane also assure signal levels are more than required for R-NAV systems use.
