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 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.

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.

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 AT-256A/ARC Antenna is used for airborne communications on
various fixed-wing and rotary-wing aircraft. The antenna is produced to
Military Specifications MIL-A-5815 and MIL-A-5815/1. The antenna is
designed to operate at the extreme temperature range of -65° F to 257° F
with intermittent operation at 302° F and can withstand a static load of 8
psi perpendicular to the blade, with an ultimate of 12 psi. The AT-256A/
ARC is protected by an anodic coating to prevent corrosion and the out-
side surfaces will resist particular erosion up to Mach 0.95. The antenna’s
sealability is tested to an altitude of 70,000 ft.
