Exelis DM N4-17 Series VOR/LOC Glide Slope Antenna for aviation with omnidirectional radiation, T.S.O. certification, and MIL-E-5400 Class 3 compliance.
The DM N4-17 Series VOR/LOC Glide Slope Antenna is designed for aircraft operating up to Mach 1.0, offering low drag, lightweight construction, and T.S.O. certification. It features a balanced loop design for omnidirectional signal reception, supporting standard VOR and area navigation. The standard system includes two antenna elements, feed cables, gaskets, and a phasing coupler. Dual output couplers are also available for enhanced functionality.
Environmental performance exceeds MIL-E-5400 Class 3 standards, making it suitable for single-engine to jet aircraft. Drag characteristics are graphed against Mach number and altitude, with data provided for various flight conditions. The antenna is T.S.O.’d and designed for reliable performance in both commercial and military applications.
