AVIONICS

The DM N4-17 VOR/LOC/Glide slope antenna is designed for general aviation, commercial, and military aircraft that operate up to Mach 1.0. DM N4-17 is designed to provide a low-cost, lightweight, and low-drag antenna for state-of-the-art avionics. This antenna's performance parameters exceeds environmental specifications of MIL-5400 Class 3 equipment; therefore, it can be installed on single engine to jet engine aircraft. The balanced loop design of the DM N4-17/N assures an omnidirectional radiation pattern at the horizon to obtain maximum signal for VOR and area navigation which provides more receiving distance and reliable system performance.

The N4-4 navigation antenna system has been designed to minimize bearing errors when receiving VOR and ILS signals. It provides increased gain at the horizon, particularly during banks, over fuselage mounted “deer horn” or “vee” antennas. It can discriminate against vertically polarized signals, and when properly installed on helicopters, it rejects rotor modulation which results in better signal to noise ratios with less errors. Constructed from magnesium tubing, this antenna is lightweight and rugged, and ideal for use on light planes and helicopters.
