About this product
The ELT antenna 2624-82 is an airborne antenna designed to transmit distress signals from an Emergency Locator Transmitter to search-and-rescue satellites and ground stations. Mounted externally, typically on the upper fuselage, it radiates on the internationally designated emergency frequencies of 406 MHz for COSPAS-SARSAT satellite detection and 121.5 MHz/243 MHz for local homing. By ensuring clear, omnidirectional signal propagation, this antenna is a lifesaving link between a downed aircraft and rescuers.

PRODUCT DESCRIPTION

2624-82

  • Multi-Band Operation: Transmits on 406 MHz for satellite detection plus 121.5 MHz and 243 MHz homing frequencies, covering all mandated ELT channels.

  • Omnidirectional Radiation Pattern: Delivers consistent signal strength in all horizontal directions, maximising the chance of detection regardless of aircraft attitude.

  • Corrosion-Resistant Materials: Constructed from fibreglass or UV-stabilised polymer with stainless fasteners to endure salt spray, UV exposure, and cleaning agents.

  • Vibration-Tolerant Design: Internally damped and mechanically secured to withstand the high-frequency vibrations inherent to flight.

  • Completes the ELT system by efficiently radiating distress signals.

  • Direct-fit replacement for aging or damaged ELT antennas on a wide range of commercial and general-aviation aircraft.

  • Serves as a critical checkpoint in annual equipment inspections, ensuring reliable distress-signal performance.

  • Satisfies FAA and ICAO requirements for installed ELT equipment in fixed-wing and rotorcraft.


  • Where is the ELT antenna typically installed on an aircraft?

It’s mounted on the upper fuselage, often near the tail, to provide an unobstructed path for both satellite and local receivers.

  • What maintenance is required for this antenna?

Inspect for physical damage, secure mounting hardware, and verify coaxial connector integrity during scheduled ELT functional tests.

  • Is this antenna compatible with all ELT units?

Yes, it interfaces via a standard coaxial connector and matches the impedance requirements of all certified ELT transmitters.
