The DM C50-17 VHF antenna features a design that provides enhanced corona threshold, corrosion protection, and drag resistance. The C50 series provides a lightweight and strong blade antenna at a lower cost for current commercial jet aircraft. The C50-17 antenna is chosen as original equipment for the Boeing 757, 767, and 777 aircraft, and can also be used on the Boeing 707, 727 737, 747; Douglas DC-8, DC-9, DC-10; Airbus A300 series and other aircraft.

The C146 Series of antennas provide GPS reception at L1 and L2 frequencies and are suitable for a wide variety of installations. It has been designed with broadband radiating elements and a quadrature feed network. The broadband elements allow the C146 Series to provide continuous coverage from L2 through L1 without regard for operating temperature.  The quadrature feed network, beyond offering excellent circular polarization and minimum axial ratio, provides low phase ripple, excellent pattern symmetry and a stable phase center.

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 DM N4-17 VOR/LOC/Glide slope antenna is designed for general aviation, commercial, and military aircraft that operate up to Mach 1.0. DM N4-17 is designed to provide a low-cost, lightweight, and low-drag antenna for state-of-the-art avionics. This antenna's performance parameters exceeds environmental specifications of MIL-5400 Class 3 equipment; therefore, it can be installed on single engine to jet engine aircraft. The balanced loop design of the DM N4-17/N assures an omnidirectional radiation pattern at the horizon to obtain maximum signal for VOR and area navigation which provides more receiving distance and reliable system performance.

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.

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.
