DMN4-15
Low Drag, VOR/LOC Balanced Loop Navigation Antenna
Frequency 108-118 MHz
(DAI Part# DMN4-15)
The DMN4-15 Antenna is designed for use on highperformance aircraft where aerodynamic drag and component weight must be held at a minimum. These systems provide increased range and reduced bearing error, versus dipole type installations. Rugged metal edges provide erosion resistance; flush glass fiber housings ensure smooth airflow and reduced drag; and each assembly is foam-filled for maximum reliability.

The DMN4-15 is intended, primarily, for new aircraft installations, but can be installed, as a retrofit, when dual-antenna capability is required.
