DM N4-4 Navigation Antenna | 108–122MHz, Single Radiating Element CI-122 and is 3-27/32 inches inThe DM N4 4 navigation antenna is a true center fed antenna which minimizes bearing errors when receiving VOR and ILS signals. The N4 4 provides considerably more gain at the horizon than fuselage mounted ""deer horn"" or ""vee"" antennas. Improved signal to noise ratio and reduced errors is due to the N4 4 greater discrimination against vertically polarized signals, and when properly installed on helicopters greater rotor modulation rejection is also
