The Chelton 935 System 7 architecture eliminates the need for separate, bulky receiver chassis inside the avionics bay. The antenna shell contains all the RF processing hardware, reducing signal loss from long coaxial runs. Specification 30 MHz to 470 MHz (Tuned in 1 kHz steps) Guard Receivers 5 Parallel Channels (Simultaneous bearing tracking) Guard RX0 (VHF) 120.000 – 130.000 MHz Guard RX1 (Maritime) 150.000 – 160.000 MHz Guard RX2 (UHF) 240.000 – 250.000 MHz Guard RX3 (SARSAT) 406.048 MHz (Full 406.025 to 406.070 MHz decoding) Guard RX4 (DSC) 156.525 MHz (Marine GMDSS Channel 70) Data Buses Supported MIL-STD-1553B, ARINC 429, RS-422 Step-by-Step Installation Procedures
Before beginning your installation, ensure you have the full Type 935 Series Datasheet and your platform-specific wiring diagrams. 935 Series Tactical DF Antenna | Chelton
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
Compatible with MS3114-16-26P, GB711 5009-1, and GB711 5009-2 connectors. chelton df 935 2 pdf install
Must be rigid and aligned exactly with the airframe (normal or inverted).
It must be mounted rigid and in line with the airframe . The system supports both normal and inverted mounting attitudes.
: For modern military configurations, link the unit via the standard MIL-STD-1553B digital databus to feed bearing data directly to multi-function cockpit displays. The Chelton 935 System 7 architecture eliminates the
: Run nearby communications gear to confirm the DF 935 remains unaffected by local electromagnetic interference.

Final step: Page 201. Leo tuned his handheld radio to 121.5 MHz (guard frequency) and walked a circle around the aircraft at 50 meters. The DF 935‑2’s display showed a spinning needle—then locked onto him at 0°, 45°, 90°, every bearing within ±2° of truth.
Proper physical, mechanical, and electrical installation ensures system accuracy (better than
Requires 16.0 to 31.5 V DC with a maximum current draw of 1.6 A.
I need to avoid technical jargon where possible, but since this is for a specific product, some technical terms are necessary. The user might not be familiar with marine electronics, so explaining terms like transducer or keel mount in simple language would be good.
