(Pins 1 and 4) loads, +150 millivolts full scale deflection with a
maximum output of +300 millivolts.
To/From: Capable of driving up to three 200 ohm parallel
(Pins 2 and 5) loads, +82 millivolts full scale deflection.

(Pins 7, 8, and 12) Bendix/King RMI (KI 229 or equivalent).
Message annunciators: Output capable of driving negative or positive logic
(Pins 9 and 11): annunciators.
Message audio: Output capable of producing 10 milliwatts into 500
(Pin 10) ohms at a frequency of 2 KHz.
RS232 data: Output capable of driving ARGUS3000/5000/7000
(Pin 13) and STORMSCOPE SERIES II with NAVAID moving
map displays and Shadin fuel management system.
Conforms to the EIA specification RS-232C.
SECTION 2 INSTALLATION CONSIDERATIONS
Careful planning and consideration of the suggestions in this section are required to
achieve the desired performance and reliability from the GPS 100.
2.1 ANTENNA CONSIDERATIONS
2.1.1 SATELLITE VISIBILITY
The GPS 100 Blade or Low Profile Antenna must be mounted on top of the aircraft in
the upright position. For best performance select a location with an unobstructed
view of the sky above the aircraft when in level flight. Figure 2-1 illustrates a typical
blade antenna installation. Recommended installation locations for the Low Profile
Antenna are the same.
Av. Kit Install. Manual
190-00004-00 Rev. G
Page 6
2.1.2 NOISE SOURCES
The antenna should be located at least 3 ft from transmitting antennas such as VHF
Comm, HF transmitter, DME, Transponder, and Radar. Cabling for the GPS 100
should not be routed near components or cabling which are sources of electrical noise.
2.1.3 ELECTRICAL BONDING
No special precautions need to be taken to provide a bonding path between the
antenna and the aircraft structure.
2.1.4 ANTENNA LIMITATIONS
The GPS 100 Blade and Low Profile Antennas are recommended for installations
where the airspeed of the aircraft will be subsonic. For aerodynamic considerations,
the Low Profile Antenna is recommended for operation above 200 kts.
2.2 RACK CONSIDERATIONS
2.2.1 ACCESSIBILITY
Plan a location which gives the pilot complete and comfortable access to the entire
keypad and which is plainly visible from the pilots perspective. Check that there is
adequate depth for the rack in the instrument panel. A location away from heating
vents or other sources of heat generation is optimal. Figure 2-2 illustrates a typical
aviation rack installation.
2.3 CABLING AND WIRING
Use only the antenna cable supplied in the installation kit. Other cabling may lead
to degraded performance. Check that there is ample space for the cabling and mating
connectors. Avoid sharp bends in cabling and routing near aircraft control cables.
2.4 ANNUNCIATORS
If the installation includes any electrical interface with other flight instruments, an
annunciator may be required. Refer to current FAA directives.

3.2 ANTENNA INSTALLATION
The Blade Antenna outline and footprint dimensions are shown in Figure 3-1. The Low
Profile Antenna outline and footprint dimensions are shown in Figure 3-1A. Both
antennas require the same Installation procedure.
A. Using the backing plate as a template, mark the location of the mounting holes and
the through hole for coax cable. Drill or punch the holes.
B. The antenna installation must provide adequate support for the antenna considering a maximum drag load of 14 lbs (at subsonic speed). Install a doubler plate to
reinforce thin skinned aircraft. Observe guidelines for acceptable installation
practices as outlined in AC 43.13-2A.
C. Seal the antenna and gasket to the fuselage using a good quality electrical grade
sealant. Use caution to insure that the antenna connector is not contaminated with
sealant. Insure that the mounting screws are fully tightened and that the antenna
base is well seated against the gasket. CAUTION: Do not use construction grade RTV
sealant or sealants containing acetic acid. These sealants may damage the electrical
connections to the antenna. Use of these type sealants may void the antenna
warranty.
3.3 CABLE INSTALLATION
A. Route the coax cable supplied to the rack location keeping in mind the recommendations of Section 2. Secure the cable in accordance with good aviation practice.
B. Trim the supplied RG-59/U cable to the desired length and install the BNC
connector (330-00017-00) per the cabling instructions on Figure 3-2.
3.4 RACK INSTALLATION
A. Figure 3-3 shows outline dimensions for the aviation rack. Install the rack in a
rectangular 6.320" x 2.000" hole in the instrument panel. Exercise caution when
installing the rack into the instrument panel. The rack is designed to facilitate removal
of the GPS 100 for portable use. Deformation of the rack may make it difficult to install
and remove the GPS 100.
B. Install the rack in the aircraft panel using four #6-32 countersunk screws and
four self-locking nuts. The screws are inserted from the inside through the holes
in the sides of the rack (see Figure 3-4).
