The Chelton DF 935-2 is a tactical direction-finding system typically installed on aircraft for Search and Rescue (SAR) or Combat SAR (CSAR) missions. Installation Guide Summary

The installation follows a two-stage approach: provisioning the aircraft and the actual hardware mounting.

Antenna Mounting: The 935 Series antenna is typically installed on the belly of the aircraft (normal) or inverted, depending on the mission profile. It requires a rigid mounting method in line with the airframe.

Cockpit Controls: The corresponding control panel or Control Display Unit (CDU) is typically installed in the center console of the cockpit. Dimensions & Clearance: Antenna Diameter: 286 mm. Antenna Height (External): 90 mm. Internal Penetration: 75 mm.

Interfacing: The system can be controlled via RS 422 using a Chelton CDU or through customer-provided interfaces such as MIL-STD-1553B, ARINC 407, or ARINC 429.

Detailed installation and technical data are typically provided in its official Technical Data Sheet and specific Installation Manuals, which are often controlled documents due to their military and aerospace applications. Technical Overview for Installation

Based on official specifications, the following parameters are critical for a standard installation:

Frequency Range: 30 MHz to 470 MHz, covering standard international distress frequencies. Physical Dimensions: Maximum footprint of approximately Mass: Approximately 3.8 kg maximum.

Power Requirements: Primary power must be between 16.0 to 31.5 V d.c., with a maximum current draw of 1.6 A.

Interfacing: The unit is compatible with the Chelton 715-40 DF Controller and supports bus-controlled (1553B) or stand-alone RS422 configurations.

Connectors: Standard installations utilize MS3114-16-26P connectors. Installation Guidelines The search for the chelton df 935 2

Mounting Attitude: The antenna should be mounted in line with the airframe, either in a normal or inverted position depending on the aircraft type.

Environmental Compliance: The system is designed to meet EUROCAE ED-14C / RTCA DO-160C standards for vibration (Cat L for fixed-wing, Cat Y for helicopters) and shock.

Interrogator Interface: For CSAR missions, ensure the system is correctly interfaced with beacon interrogators such as the PRC-112G, PRC-434, or URX3000 to facilitate covert rescue. Official Documentation & Support
