N4-33 Low Drag Balanced Loop VOR/LOC Antenna | 108–118MHz, Single Radiating Element

Product Description

The N4-33 VOR/LOC antenna has a low drag balanced loop design for use on high performance aircraft where aerodynamic drag must be kept to a minimum. The N4-15 antenna provides increased range and reduced barring error. Rugged construction provides erosion resistance; a flush fiberglass housing improves aerodynamics; and a foam-filled assembly ensures maximum durability.

The N4-33 is intended for retrofit installation or antenna modifications on existing aircraft. Dual antenna capability can be achieved by using a hybrid coupler such as the H21 series couplers.
 

This VOR/LOC balance loop blade antenna (EDMO# DM N4-33-3) is a single radiating element.
