DM N4-17/N WITH TWO OUTPUTS (DM N4-17/P)
|
The DM N4-17 VOR/LOC/Glide Slope antenna is designed for general
aviation, commercial, and military aircraft that operate up to Mach
1.0. The DM N4-17 is designed and qualified to provide a low-cost,
lightweight, low-drag antenna for state-of-the-art avionics systems.
The
antenna is not only T.S.O.'d, its performance parameters exceed the
enfironmental specifications of MIL-E-5400 Class 3 equipment.
Therefore, the DM N4-17 can be installed on single engine to jet engine
aircraft.
The balanced loop design of the DM N4-17 assures an
omnidirectional radiation pattern at the horizon to obtain the maximum
signal for standard VOR and area navigation, which in turn provides
more receiving distance and reliable system performance.
The
standard system is the DM N4-17/N, which consists of two antenna
elements (DM N4-17-1/N), two feed cables and gaskets (DM U212-1 and DM
U23501 respectively), and a phasing coupler (DM N4-17-2). Dual output
couplers (DM N4-17-4) are available as well. More Info...

GLIDE SLOPE ANTENNA/TNC (DM N25-1)
|
The DM N25 Series of glide slope antennas employ a grounded, center-fed loop as the radiating element. The resulting radiation patterns are symmetrical.
All DM N25 Series antennas provide complete lightning protection for the associated receivers. They are suitable for mounting either externally, or within a nose radome. The inherent 180° pattern beam may be modified slightly by the geometry surrounding the installation. The DM N25 antennas are recommended for installations in close proximity to radar dish installations since the antenna's (glide slope) sensitivity is relatively unaffected by dish motion.
It should be noted that the DM N25 antennas have mounting dimension requirements which are identical to similar function Collins and Sensor antennas. Since the mounting base-to-tip dimension of the DM N25 antenna is slightly less than the Collins and Sensor units, the DM N25 antenna is a direct replacement.

LOOP TYPE/DUAL OUTPUT/C CONN (DM N25-2)
|
The DM N25 Series of glide slope antennas employ a grounded, center-fed loop as the radiating element. The resulting radiation patterns are symmetrical. The DM N25-2 is a dual connector version which incorporates a hybrid. This circuitry effectively isolates the two associated receiving systems providing protection against disablement of both systems in the event of failure in one system. The radiation pattern associated with each DM N25-2 antenna port is identical, so that no coupler drop-out problem during automatic landing occurs.

MILITARY VERSION/DM C60-171 (DM C60-3)
|
|
The DM C60 is a vertically polarized VHF communications antenna designed for either top or bottom fuselage mounting. The antenna covers the frequency range of 116 to 152 MHz for both transmitting and receiving applications. Electrical elements of the antenna are completely sealed by foamed-in-place resin within an outer fiberglass housing. As a result, the antenna is rugged enough for use on both commerical and general aviation aircraft. More Info...

SPECIAL ORDER ANTENNA (DM N9-9)
|
The DM N9-Series antenna provides a dual band design for both Localizer/VOR and Glide Slope systems for installation within nose radomes on high performance aircraft.
The design incorporates common radiating elements into a single monolithic structure for mounting either on a bulkhead within a radome or to the radome directly. The antenna is designed with the radiating elements attached to a single curved dielectric window to provide support. In some cases, reinforcing ribs provide structural rigidity and mounting adaptability to the bulkhead for mechanical attachment and electrical grounding to the airframe.
The DM N9-Series is a balanced bent-back dipole antenna which renders it immune from the nose radar motion. In addition to excellent Localizer and Glide Slope patterns, many users utilize the Localizer output for forward-looking VOR as well.

VOR/LOC BAL LOOP "TOWEL BAR" GREEN (DM N4-4)
|
The DM N4-4 Antenna System has been designed to minimize bearing errors in the reception of VOR and ILS signals. It provides considerably more gain at the horizon (particularly during banks) than do fuselage mounted "deerhorn" or "vee" antennas. It has substantially greater discrimination against vertically polarized signals; and when properly installed on helicopters it provides much greater rejection of rotor modulation than can be obtained with these other antennas. As a result, it provides better signal to noise ratios and smaller errors than is otherwise available.
The DM N4-4 Antenna consists of two (approximately semicircular) center-fed half-loops and cable harness. Because the DM N4-4 has been designed specifically for light planes and helicopters, lightweight rugged construction has been stressed. It is built of round magnesium tubing and weigs only 2 pounds.

VOR/LOC BALANCED LOOP ANTENNA (DM N4-7)
|
Increased VOR/LOC range and minimized bearing errors can be achieved with any airborne VOR receiver through the use of these DM N4-7 and DM N4-8.
Each DM N4 system utilizes two center-fed, half-loops and a cable harness, enabling "closed loop" current flow. This provides better signal-to-noise ratios and higher rejection of cross-polarized signals. In terms of system performance, this means that smaller signals can ve received and bearing errors, particularly those induced by banking, are greatly reduced.
These rugged antennas have been selected and service proven on such aircraft as the 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.
