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 150.
2.1 ANTENNA CONSIDERATIONS
2.1.1 SATELLITE VISIBILITY
The GPS 150 GA 56 Antenna must be mounted on top of the aircraft. 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 antenna installation.
For rotorcraft, locate the GA 56 antenna:
1) As far from the main rotor hub as possible. This reduces the percentage of time
the blade blocks the antenna.
2) As far below the blade surface as possible if installing the antenna under the blade.
This reduces signal distortion caused by the blades.
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 150
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
GARMIN'S GA 56 Antennas are recommended for installations where the airspeed of
the aircraft will be subsonic.
2.1.5 VHF COMM INTERFERENCE
On many panel-mounted aircraft the VHF COMM radiates strong harmonics from the
unit and the antenna. If the antenna is found to be the problem, a 1.57542 GHz notch
filter (GPN 330-00067-00) may be installed in the VHF COMM coax, as close to the
COMM as possible. If the box is found to be radiating, the following can be done:
1) Place the antenna as far from the VHF COMM unit and antenna as
possible.
Av. Kit Install. Manual
190-00026-00 Rev. Q
Page 8
2) Replace or clean VHF COMM rack connector to assure good coax ground.
3) Place a grounding brace between the GPS 150, VHF COMM, and ground.
4) Shield the VHF COMM wiring harness.
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 pilot’s 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
The recommended antenna cable type is M17/155-0001 (RG-58A/U) per MIL-C-17.
Maximum allowable length for this cable type is 40 feet. Other cable types with 50
ohms nominal impedance and longer lengths can be used, provided the installer
insures that the attenuation does not exceed 10dB at 1.5 GHz for the specific
installation. 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 COOLING AIR
Cooling air is not required for the GPS 150, however as with any electronic equipment,
reduced operating temperature can contribute to increased reliability. Additionally,
location of the GPS 150 in a stack of other power dissipating equipment can produce
unacceptably high ambient air temperatures around the unit. A 5/8 inch diameter
air fitting is provided on the rear of the mounting rack for the purpose of admitting
cooling air under such conditions.
2.5 ANNUNCIATORS
If the installation includes any electrical interface with other flight instruments, an
annunciator may be required. Refer to current FAA directives.
2.6 EXTERNAL ALTITUDE INPUT
Pressure altitude input from an external source may benefit GPS 150 system
performance during times of minimal satellite coverage or poor satellite geometry.
Provisions for RS-232 compatible serial altitude input are described in the Interfaces
section (Section 1.2.3) of this manual.

3.2 ANTENNA INSTALLATION
The GA 56 Antenna outline and footprint dimensions are shown in Figures 3-1 and
3-2.
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 5 lbs. for the GA 56 antennas (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

190-00026-00 Rev. Q
Page 10
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 to the rack location keeping in mind the recommendations
of Section 2. Secure the cable in accordance with good aviation practice.
B. Trim the coaxial cable to the desired length and install the BNC connector (330-
00087-00) per the cabling instructions on Figure 3-3. If the connector is provided
by the installer, follow the connector manufacturer's instructions for cable
preparation.
C. Contacts for the 37-pin connector must be crimped into the individual wires of the
aircraft wiring harness. The following table lists recommended crimp tools:
Non- GARMIN part numbers shown are not maintained by GARMIN and consequently
are subject to change without notice.
See Appendix B for information regarding obsolete stamped type contacts.
