The ELT-04 Whip Antenna is designed to support emergency transmissions on both 406 MHz and 121.5 MHz when used with the E-04 emergency locator transmitter. Its dual-frequency monopole design allows a single antenna to handle both satellite alerting and local homing signals.
The antenna is suitable for external aircraft installation and is rated for operation at airspeeds up to 260 knots. This makes it appropriate for a wide range of general aviation aircraft where compliant ELT antenna performance is required.
When installed in accordance with applicable ELT and aircraft installation instructions, the ELT-04 Whip Antenna provides reliable RF performance to support emergency locator transmitter operation as part of an approved ELT system.
