DM N4-4 Navigation Antenna | 108 MHz to 122 MHz, 50Ω, BNC
HARRIS CORP
EDMO#: DM N4-4
MFR#: DM N4-4
Description
The DM 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, than fuselage mounted “deer horn” or “vee” antennas. It can discriminates 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.
