The is a high-performance, broadband Direction Finding (DF) Antenna System . Designed primarily for airborne and marine applications, it is part of the Chelton (Cobham) family of antenna solutions. The "DF" stands for Direction Finding, indicating the unit's capability to determine the bearing of an incoming radio signal. The DF 935 is typically characterized by its log-periodic or dipole array design, allowing it to operate efficiently across a wide frequency spectrum (often VHF/UHF bands).

Installation is generally performed under a modification order (such as ) and requires specific engineering documentation: Mechanical Installation: chelton df 935 2 pdf install

The Chelton DF-935-2 is a highly sophisticated tactical Direction Finder system, providing crucial search and rescue capabilities. Its installation is a complex, multi-step process that demands a thorough understanding of its technical specifications, careful mechanical integration, precise electrical wiring, and rigorous post-installation testing.

Therefore, the "Chelton DF 935 2 PDF" refers to a specific variant of the antenna optimized for higher precision direction finding with dual-polarization capabilities.

The 935 DF includes an integral synthesised receiver covering a broad frequency range of , together with five Guard Receivers to monitor pre-defined distress frequencies. Crucially, bearings may be taken on all six receivers simultaneously, providing comprehensive situational awareness. The system also provides data decoding for COSPAS-SARSAT messages and for Marine DSC messages, making it a versatile tool for both Search and Rescue (SAR) and Combat SAR (CSAR) missions. “It can interface with Personnel Survival Radios (PSR)

messages. It handles SARSAT data across standard frequencies without requiring operator scanning. Combat Capabilities

Supports COSPAS-SARSAT message decoding and marine DSC messages. Accuracy: Delivers a bearing accuracy of better than 5∘5 raised to the composed with power

Understanding these specs is the first step. A common question from installers is whether the system can be integrated with an existing avionics bus, and the answer is yes for bus-controlled setups. Next, we'll move into the practical steps of preparing for the physical installation.

: Flexible interface options include RS-422, ARINC 429, and MIL-STD-1553B , allowing for bus-controlled or stand-alone operations. Critical Technical Specifications Specification Frequency Range 30 MHz – 470 MHz Primary Power 16 to 31.5 VDC, 1.6A max Antenna Weight 3.8 kg (maximum) Antenna Dimensions 286 mm diameter x 90 mm height Altitude Rating Up to 25,000 feet

The 935 Series is engineered for flexibility, capable of operating in both bus-controlled (i.e., integrated with a wider aircraft management system) and stand-alone configurations, making it suitable for a wide range of aircraft types and missions.

Two hours later, the physical install was done. The DF 935-2 was bolted to the airframe’s ground plane, its three antennas (left-right-forward array, the manual explained) aimed precisely at 0°, 120°, and 240° relative to the aircraft’s longitudinal axis. He’d used a laser protractor. The hangar cat, Schrödinger, watched from a tool chest, unimpressed.

: Ensure a low-resistance electrical bond exists between the unit’s base plate and the airframe metal. Poor grounding compromises the DEF-STAN 59-41 EMC rating, injecting unwanted electrical noise into the tracking receivers. 5. Post-Installation Testing and Calibration
