Radar interrogator antenna
The AT-884B/APX-44 Antenna is a Radar Interrogation antenna designed to receive vertically polarized signals at 1010-1030 MHz and radiate vertically polarized signals at 1010-1110 MHz. This antenna is constructed for capability of functioning during all normal maneuvers of the
aircraft at all azimuth headings in respect to any radial to the interrogating radar location. The AT-884B is produced to the requirements of Military
Specification MIL-T-55046. The antenna has an operating temperature range of -65° F to 130° F, an operating altitude of up to 30,000 ft, and is constructed to meet the environmental requirements of Military Specification MIL-E-5400. The antenna’s outside surfaces are protected with
a chemical resistant CARC green coating.
AT-640A / ARN Marker Beacon 75hz
The AT-640A/ARN Antenna is a receive-only VHF Marker Beacon antenna used on both fixed- wing and rotary-wing aircraft. The antenna will meet the requirements of Military Specification MIL-A-5999 for electrical and environmental performance. The antenna is finished with a white Skydrol resistant polyurethane paint in accordance with Military Specification MIL-C-81773.
The AT-640A has an operating temperature of -40° F to 140° F and experiences a drag force
of 0.22 lb at airspeeds of 400 mph. Precipitation s tatic is minimized through the use of a foam-filled fiberglass construction. The foam also reduces the effects
of vibration, shock and temperature extremes. Marker beacon

The AT-740/A Antenna is used for airborne radar interrogation on various fixed-wing aircraft. The antenna is produced to Military Specification MIL-A-25707 and MIL-A-25707/1. The antenna is designed to operate at the extreme temperature range of -67° F to 302° F. The AT-740/A is a flush-mounted, cavity-back slot antenna constructed
of aluminum with a fiberglass radome. The antenna has a
type BNC sampling probe and is protected by an anodic coating to prevent corrosion.
The AS-3916/VRC Antenna is a Survivable Low Profile version of the AS-3900A/VRC Antenna. It is used with the SINCGARS Radio System on vehicles which launch TOW Anti-Armor Missiles where the back-blast of the missile launchers would damage the AS-3900A/VRC Antenna. The AS-3916/VRC can withstand the application of 20,000 VRMS to the antenna element without adverse affect to the antenna or radio.
The AS-3916/VRC is produced to the U.S. Army CECOM Specification A3180155 and was designed, developed, and produced under a CECOM Request Proposal
by R.A. Miller. The antenna has a higher power capacity to allow multiplexing of up to four (4) radios to a
single antenna. This eliminates a co-site problem of multiple antennas interfering with each other.

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. Current- ly in use on business, commercial and military jet aircraft, the DM NI50 antennas have clear advantages over the other current designs:
-Extremely high side strength guards against breakage by ground handling gear. -Completely sealed construction prevents failure from moisture intrusion. -Lightning protection circuits prevent damage to antenna and safeguard electronic equipment.
The AT-1108/ARC Antenna is a combined VHF/UHF airborne communications antenna designed for usage airspeeds of less than Mach 1. The antenna housing is fiberglass epoxy, designed to withstand the exposure to sand and dust particles of desert areas and is foam-filled to reduce the effect of extreme temperature changes, extreme humidity, and excessive shock and vibration. The AT-1108/ ARC is produced to Military Specification MIL-A-55680 and has continuous operation altitudes of up to 50,000 ft and temperatures between -65° F and 131° F. The antenna can withstand the impact shock of 30g and the steady-state acceleration of 6g. The isolation between the bands is > 40 dB. A gasket for RF shielding and positive sealing is included. The antenna is coated with a Skydrol resistant lusterless CARC black paint.

The DM N25 Series of glide slope antennas employ a grounded, center fed loop as the radiating element. The resulting rediation patterns are symmetrical. The DM N25-2 is a dual connector version which incorporates a hybrid. This circuitry effectively isolates the two associated receiving system providing providing protec- tion against disablement of both systems in the event of failure in one syatem. The radiation pattern associated with each DM N-2 antenna port is identical, so that no coupler drop out problem during automatic landing occurs.
All DM N25 Series antennas provide complete lightning proection for the associated receivers. They are suitable for mounting either externally, or within a nose radome. The inherent 180 deg. 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.
