Supports integration via MIL-STD-1553B , ARINC 429 , ARINC 407 , and RS-422 serial data links.
For integrated military tactical data link networks.
The physical installation footprint of the antenna unit dictates its placement on the fuselage: : 286 mm External Height (Above Airframe) : 90 mm Internal Penetration (Below Airframe) : 75 mm Mounting Position and Attitude
This guide provides a vital framework for understanding, planning, and executing that installation. The immediate next step is to contact Chelton directly or your platform's OEM to secure the official, approved documentation for your specific installation. This is not just a best practice—it is a non-negotiable requirement for the safety of the aircraft and the effectiveness of the mission. chelton df 935 2 pdf install
Most issues during a DF installation stem from wiring errors or software configuration. Here's how to resolve the most frequent problems you might encounter:
Mark the skin utilizing the precise layout pattern provided in the official Chelton Avionics Installation Manual .
Once securely mounted and wired, complete the standard verification workflow before signing off on the installation: Supports integration via MIL-STD-1553B , ARINC 429 ,
Better than 5° RMS (highly dependent on quality of placement and proper airframe bonding). Step 1: Mechanical Installation and Airframe Mounting
If you have the PDF installation manual (often labeled IM or Installation Manual ), the process follows the standard TSO (Technical Standard Order) avionics workflow.

The first step is assessing the host platform. The DF system must be installed with a rigid mounting in line with the airframe, either normal or inverted. The mounting method and plinth options can be customized to keep protrusion as low as possible while maintaining functionality, especially for operations at lower altitudes.
