DM N4-7 High Sensitivity Balanced Loop VOR/LOC Antenna | BNC Connector, 6-hole Mount, Black Finish

Product Description

The DM N4-7 VOR/LOC navigation antenna is a true center-fed balanced loop antenna with a high sensitivity and low bearing errors. The N4-7 system consists of two center-fed half-loops and a cable which enables a closed loop current flow allowing for improved signal to noise ratio and higher cross-polarized signal rejection. These rugged antennas have proven reliable service on aircraft such as Lockheed Jet-star, P-3A, and C-141 Starlifter, Bell UH1B helicopter, Sikorsky H34 helicopter, Convair 340, Aero Commander, North American Sabreliner, Douglas DC-3, Beech King Air and many other corporate and commercial aircraft.
