NAVIGATION ANTENNAS EDO ANTENNAS & ACCESSORIES aviall.com North America and AOG 1.800.AVIALL.1 International Sales 1.800.AVIALL.3 or +1 972.586.1985 1237 DM NI7 series L-band flush antennas. MEETS MIL-E-5400 AND MIL-T-5422C; IMMERSION TESTED TO MIL-E-5272A; MEETS MIL-A-256612 (AT-720/A ONLY); TSO C74 (ATC TRANSPONDER) AND C66 (DME) APPROVED. Reduced maintenance costs are achieved through the use of this low-profile, all-metal blade as a result of its unequalled mechanical strength and built-in reliability. Currently in use on business, commercial and military jet aircraft, the DM NI7 antennas have clear advantages over the other current designs: extremely high side-load strength guards against breakage by ground handling gear; completely sealed con- struction prevents failure from moisture intrusion; lightning protection circuits prevent damage to antenna and safeguard electronic equipment. Models of the DM NI7 antenna are directly interchangeable with virtually all L-band blade and flush mounting antennas currently in service on commercial and military aircraft.

HN male 20.00" 1.4:1 from 1030-1090 MHz DMNI7-8 DM NI7 L-band flush antenna 960-1220 Mhz 1.5:1 at 960-1220 MHz 21 oz. HN male 71.50" 1.4:1 from 1030-1090 MHz DM N43 series marker beacon antennas. TSO C35c APPROVED. The DM N43 series are rugged, lightweight antennas for the reception of 75 MHz marker beacon signals. These low-drag antennas are designed for simple external mounting and require no cutting of airframe structural members. The largest hole required in the skin is for the connector. Moisture-proofing is assured by the dielectric foam filled, white polyester-fiberglass radomes. These Skydrol-resistant housings are fitted with metal leading edges for erosion protection. The DM N43 antennas are designed to meet the performance specifications of antennas AT-134 and AT-536. Part No. Description Freq.

BNC female marker beach antenna <2.0:1 at 75 MHz (UG-89) DM NI24 and DM NI29 series L-band blade antennas. TSO C74 (ATC TRANSPONDER) AND C66 (DME) APPROVED. These L-band blades utilize a new concept of antenna design and manufacture which makes them ideal for commercial as well as military application. The radiating element is encapsulated in an epoxy dielectric body by a transfer molding process. This simple design has several notable advantages: moisture proof (the antenna is impervious to moisture penetration either by direct immersion or by extended exposure to high-humidity conditions); rugged design (the interlocked mounting base and radiating element, molded into the dielectric body, are a completely unified, integral, and rugged assembly); economy (the molding process is a high-production technique, substantially reducing antenna cost). The antennas have been used with various equipment such as DME, IFF, TACAN, Telemetry, and Beacon. The DM NI29-15, DM NI29-19, and DM NI29- 18, have been designed to provide ideal performance for various Flight-Fone Systems.
