1 GENERAL DESCRIPTION
1.1 Introduction
This manual presents mechanical and electrical installation requirements for installing the
GTS 8XX/GPA 65 Traffic Advisory System (TAS) and Traffic Collision Avoidance System (TCAS I).
1.2 Equipment Description
The GTS 8XX is a microprocessor-based Line Replaceable Unit (LRU) that uses active interrogations of
Mode S (GTS 820 and GTS 850 only) and Mode C transponders to provide Traffic Advisories to the
pilot. The GTS 820 and GTS 850 include a GPA 65 power amplifier/low-noise amplifier (PA/LNA)
module, which allows for up to 40 nm of active surveillance range as well as Mode S interrogation
capability. When installed with a 1090 MHz ADS-B transmit class of equipment the GTS 8XX also
utilizes passive surveillance. Traffic is displayed on an external MFD via ARINC 429 and/or Ethernet
High Speed Data Bus (HSDB). An aural alert is also provided to inform the crew a traffic advisory (TA)
will be displayed.
A top-mounted directional antenna is used to derive bearing of the intruder aircraft, which is displayed
with relative altitude to own aircraft. Top antenna transmitted interrogations are directional, reducing the
number of transponders that receive the interrogation thus reducing potential garble on the 1090 MHz
band. Optional bottom antenna transmit interrogations are omni directional, using a monopole antenna
(recommended for fixed gear installations) or a directional antenna (recommended for retractable gear
installations). A bottom directional antenna installation gives the benefit of intruder bearing visibility for
targets that are shaded from the top directional antenna.

2.2 Installation Considerations
Fabrication of a wiring harness is required. Sound mechanical and electrical methods and practices are
required for installation of the GTS 8XX/GPS 65.
2.2.1 Antenna Considerations
Antenna installations on pressurized cabin aircraft require FAA approved installation design and
engineering substantiation data whenever such antenna installations incorporate alteration (penetration) of
the cabin pressure vessel by connector holes and/or mounting arrangements. For needed engineering
support pertaining to the design and approval of such pressurized aircraft antenna installations, it is
recommended that the installer proceed according to any of the following listed alternatives:
1. Obtain approved antenna installation design data from the aircraft manufacturer.
2. Obtain an FAA approved STC, pertaining to, and valid for the antenna installation.
3. Contact the FAA Aircraft Certification Office in the appropriate Region and request identification
of FAA Designated Engineering Representatives (DERs) who are authorized to prepare and
approve the required antenna installation engineering data.
4. Obtain FAA Advisory Circular AC-183C and identify a DER from the roster of individuals in it.
5. Contact an aviation industry organization such as the Aircraft Electronics Association for
assistance.
For all composite aircraft, antenna installation requires that a ground plane be fabricated on the internal
surface of the aircraft directly under the antenna. The TAS/TCAS antenna pattern is dependent upon a
ground plane under the antenna. The minimum recommended antenna ground plane dimensions are
18” x 18” for composite aircraft.
A fabricated doubler plate assembly supplied by the installing agent or antenna vendor may be required
inside the fuselage to complete the antenna hardware installation.
NOTE
For all GTS 8XX installations, a monopole antenna is recommended if installing an
optional bottom mounted antenna on a fixed-gear aircraft, while retractable-gear aircraft
may use either a monopole or a directional bottom mounted antenna. The target bearing
accuracy may be degraded for bottom directional antenna installations on aircraft with
fixed gear.
Page 2-4 GTS 8XX/GPA 65 Installation Manual
Revision 4TP 190-00587-00
2.2.1.1 TAS/TCAS Antenna Location
To achieve proper interrogation and surveillance volumes the following GTS 8XX antenna installation
guidelines should be followed.
The GTS 8XX requires a top-mounted directional antenna. An optional bottom mounted directional or
L-band monopole antenna can be installed in conjunction with the top-mounted directional antenna.
Antenna locations are critical to maintain the surveillance coverage across all azimuth and elevation
angles. Locations shall be chosen so the top mounted and bottom mounted antenna will represent same
range and bearing to an intruder. The mounting location, geometry, and surroundings of the antenna can
affect the system performance. The following guidance provides information to aid the installer in
ensuring that the most optimum location is selected for the installation of the antenna. Because meeting
all of these installations guidelines may not be possible on all aircraft, these guidelines are listed in order
of importance to achieve optimum performance. The installer must use best judgment to balance the
installation guidelines.
Installations must be thoroughly tested to verify that performance degradation as a result of antenna
placement is not an issue for the TAS/TCAS system as well as other systems.
1. As far as physically possible, the top directional antenna shall be mounted at the most forward
location.
2. The TAS/TCAS antenna(s) shall be mounted on the aircraft skin so that the horizontal base is
horizontal to within +/-5° in longitudinal and lateral axes when the aircraft is in level flight.
3. The TAS/TCAS antenna(s) shall be mounted on a flat section of the fuselage to reduce the gap
formed between the base plate and the fuselage when normal mounting torque is applied.
4. It is recommended that all antennas be mounted at least 20 inches away (measured from center to
center) from the TAS/TCAS antenna(s).
5. Ground plane considerations shall include minimization of any discontinuities such as overlapped
un-riveted airframe skins, cowlings, or hatches. It is recommended that all such discontinuities be
at least 18 inches from the nearest edge of the TAS/TCAS antenna.
6. For installations using a bottom mounted antenna, it is recommended that the top and bottom
antennas be located near the same vertical line through the aircraft such that they represent the
same range and bearing to an intruder.
7. The top and bottom mounted TAS/TCAS Antenna shall be as close as possible to the aircraft
centerline.
8. It is recommended that no antenna be mounted in front of the TAS/TCAS antenna(s).

190-00587-00 Revision 4TP
2.3 Electrical Bonding
Electrical equipment, supporting brackets, and racks should be electrically bonded to the aircraft’s main
structure. Refer to SAE ARP 1870 section 5 when surface preparation is required to achieve electrical
bond. The electrical bond should achieve direct current (DC) resistance less than or equal to 2.5
milliohms to local structure to where the equipment is mounted. Compliance should be verified by
inspection using a calibrated milliohm meter. An equivalent OEM procedure may also be substituted.
There may be OEM-specific reasons for electrically isolating equipment or having a higher bond
resistance. These reasons should be rationalized upon installation approval. In general, Garmin
recommends that all GTS 8XX equipment be electrically bonded.
The antenna ground plane and doubler plate must be electrically bonded to the antenna baseplate. The
electrical bond must achieve direct current (DC) resistance less than or equal to 2.5 milliohms.
For composite aircraft, the antenna baseplate must be electrically bonded to the common ground of other
installed equipment for lightning purposes. This can be achieved through the antenna mounting screws.
2.4 Cabling and Wiring
Use #24 AWG or larger diameter wire for all connections unless otherwise specified. The minimum
diameter wire size for all GTS 8XX installation wiring is #24 AWG, except in the case of Aircraft Power
and Aircraft Ground and both shall be a minimum of #18 AWG. Refer to Table 2-1 for GPA 65 wiring
specifications.
A single circuit breaker shall be dedicated to the GTS 8XX unless specifically approved by the
manufacturer on a case by case basis, or allowed by the STC. Do not attempt to combine more than one
unit on the same circuit breaker unless it is specified on an aircraft manufacturer approved drawing, or
STC documentation, for the specific installation requiring a combined configuration.
The current rating for each standard density 37-pin D-sub connector pin is 5 Amps, and the current rating
for each high density 78-pin D-sub connector pin is 2 Amps. A 14 Vdc installation requires a minimum
of two Aircraft Power and two Aircraft Ground wires in the harness. A 28 Vdc installation requires a
minimum of one Aircraft Power and one Aircraft Ground wires in the harness.
It is the responsibility of the installing agency to take into account wire sizing based on the length and
number of wires, current draw of the unit, D-sub connector pin current rating, and the unit’s internal
protection requirements.
NOTE

The contacts used to facilitate the use of #18 AWG wire for Aircraft Power and Aircraft Ground have
expanded-diameter barrels that extend out from the back of the standard D-sub connector body to
accommodate the larger diameter wire. Appropriate heat shrink tubing should be utilized to provide
sufficient insulation from surrounding contacts.
Ensure that routing of the wiring does not come in contact with sources of heat, RF or EMI interference.
Check that there is ample space for the cabling and mating connectors. Avoid sharp bends in cabling and
routing near aircraft control cables.
NOTE
All appliance to antenna cabling shall bundle top channels as a group and bottom
channels as a group to prevent incorrect wiring between top and bottom channels.
A visual inspection shall be performed to verify that all coaxial cables are connected properly, before
attempting to operate the equipment.

NOTE
Use of QMA connectors other than those specified in Table 2-2 for coaxial cable
assemblies fabricated by the installing agency using either M17/128-RG400 or
M17/60-RG142 coaxial cable will constitute the cable assemblies as being
non-compliant with the manufacturer’s installation standards.
2.4.1.5 Coaxial Cable Assembly Repair and Rework
In the event that an individual coaxial cable assembly requires rework, between a GTS 800 jack and
antenna jack, a TOP GTS820/850 jack and GPA 65 jack or a BTM GTS 820/850 jack and antenna jack,
the repairable coaxial cable may be reduced in length a maximum of two inches.
In the event that rework is required on a coaxial cable assembly between a GPA 65 jack and antenna jack
on a GTS 820/850 installation, complete replacement of the cable assembly shall be required in lieu of
rework.
Refer to Table 2-3 for recommended maximum cable assembly lengths for cable assemblies fabricated by
the installer.

3 INSTALLATION PROCEDURE
3.1 Unpacking Unit
Carefully unpack the equipment and make a visual inspection of the unit for evidence of damage incurred
during shipment. If the unit is damaged, notify the carrier and file a claim. To justify a claim, save the
original shipping container and all packing materials. Do not return the unit to Garmin until the carrier
has authorized the claim. Retain the original shipping containers for storage. If the original containers
are not available, a separate cardboard container should be prepared that is large enough to accommodate
sufficient packing material to prevent movement.
3.2 Wiring Harness Installation
Allow adequate space for installation of cables and connectors. The installer shall supply and fabricate all
of the cables. All electrical connections are made through two 78-pin high-density D subminiature
connectors, one 37-pin standard density connector, and one 19-pin circular connector (GTS 820 and
GTS 850 only). Section 4 defines the electrical characteristics of all input and output signals. Required
connectors and associated hardware are supplied with the connector kit.
See Appendix B for examples of interconnect wiring diagrams. Construct the actual harness in

NOTES
1. Non-Garmin part numbers shown are not maintained by Garmin and consequently are subject
to change without notice.
2. Extracting a contact used for #18 AWG requires that the wire barrel be cut off from the
contact. It may also be necessary to push the pin out from the face of the connector when using
and extractor due to the absence of the wire. A new contact must be used when reassembling
the connector.
3. Contacts for #16 AWG and Contact Crimp Tooling: Contact Garmin for information regarding
contacts and contact crimp tooling. Note 2 also applies.
4. Alternate Contacts for Use With #18 AWG: As an alternative to the Positronic contacts listed,
and provided in the installation kit, if the need arises the installer may use contacts made by
ITT Cannon under P/N 031-1007-001. The particular contact is not compatible with the
Daniels MFG K774, Positronics 9502-11 or Amphenol 9502-11 positioners, though. Only use
postioner part numbers Daniels MFG K250, ITT Cannon 980-0005-722 and Astro 616245.
3.3 QMA Connector Insertion and Removal
To engage the QMA connectors, use the outer sleeve of the QMA plug to align the connectors and insert
the plug onto the jack until it snaps into place. There will be an audible “snap” when the connectors are
fully engaged, refer to Figure 3-1. No tools are required for the insertion of a QMA plug onto a QMA
jack.
Figure 3-1. Engaging QMA Connectors

Page 3-4 GTS 8XX/GPA 65 Installation Manual
Revision 4TP 190-00587-00
CAUTION
Do not pull on the cable when removing the QMA plug from the jack.
To disengage the QMA connectors, pull back firmly on the outer sleeve of the QMA plug away from the
jack connector (refer to Figure 3-2). This will disengage the locking mechanism that secures the plug
connector to the jack connector. Pulling on or disengaging the QMA connectors in any other way is not
recommended and may cause damage to both the connectors and coaxial cable.
Figure 3-2. Disengaging QMA Connectors
CAUTION
Side-loading of the QMA connectors should be avoided during both the insertion and
removal of the connectors. It is recommended service loops with adequate length of
coaxial cable be used to insure that side-loading on the connectors is minimized once the
cable is securely fastened in the aircraft. Excessive side-loading may result in damage or
premature failure of the QMA connectors.

3.5.5 Ramp Test and Return To Service Test
Using a ramp tester, such as a TIC TR220 or equivalent, make the following setup and measurements to
verify GTS 8XX operational and surveillance functional.
To select a scenario that will properly converge and intercept the GTS 8XX, the GTS 8XX must be in
Ground Test mode. To enable Ground Test mode, the aircraft must be on the ground and the GTS 8XX
must be in Normal System mode and in Standby.
Activate ground test mode by clicking ‘Enable’ in the Ground Test field on the Normal tab of the GTS
8XX Install Tool.
Figure 3-8. Ground Test
This simulates the GTS to be airborne at 50,000 ft with magnetic heading of 0°.
NOTE
The GTS 8XX will not accept the Ground Test command unless the unit is in Standby and
the squat switch indicates the aircraft is on the ground.
Position the test set directional antenna with a clear line of sight to the GTS 8XX antenna at 90 degrees.
With the GTS 8XX powered up and in Standby mode indicated on the CDTI, cycle the GTS 800 to
“Operate”.
Select the following scenario:
Set the intruder type as ATCRBS.
Intruder Start Distance Intruder Start Altitude Vertical Speed Velocity
10 NM 50,000 ft 0 fpm. 360 Kts
Initiate the intruder scenario and observe the following:
• Traffic should be acquired at approximately 10 NM at 90 degree bearing and co-altitude.
Observe intruder closes on own aircraft at a rate of .1 NM/sec.
• The intruder should transition from Other Traffic (displayed as an open diamond with 00
displayed above), to proximate traffic (displayed as a filled white diamond with 00
displayed above), to a Traffic Advisory (TA) alarm.
• The appropriate TA symbology (yellow filled circle with 00 displayed above, and an audio
annunciation of "Traffic! 3 O'clock! At Altitude! 3 Miles!"), displayed when the
intruder approaches within 3 NM.

190-00587-00 Revision 4TP
3.5.6 Antenna Verification
The first step in antenna verification is to verify auto-calibration operates without indicating a fault.
1. With the GTS 8XX powered up and “Standby” indicated on the CDTI cycle the GTS 8XX to
“Operate”. Each time the GTS 8XX transitions between these modes a self test of the antenna
circuit is initialized. If the antenna connection is not correct the CDTI will display “Failure”
indicating it will be necessary to recheck the antenna coaxial connections. If the CDTI
displays “Operate” without indicating a fault, proceed to the next step of antenna verification.
Using a ramp tester, such as a TIC TR220 or equivalent, make the following set up and measurements to
assure the antenna is properly connected and the GTS 8XX is operational.
2. Position the test set directional antenna with a clear line of sight to the GTS8XX antenna.
3. Ensure that the transmitter or receiver (RX/TX) that you are testing is significantly closer to the
ramp tester than another operating RX/TX, or erroneous and inaccurate results may occur. All
four quadrants (forward, starboard, aft, and port) will be similarly tested to verify bearing of
simulated intruder supplied via the ramp tester are correctly displayed on the CDTI.
4. Using the ramp tester, select the proper antenna gain and distance to aircraft.
5. Position ramp test set at 0 degrees.
6. Turn the test set on.
7. Connect the directional antenna to the ramp test set.
8. Set the multifunction test set to perform “TCAS” testing. Configure the GTS 8XX to the
normal operating mode.
9. Program a static intruder per the following scenario:
NOTE
See ramp test set operators manual to set the following parameters
Intruder Start Distance Intruder Start Altitude Vertical Speed Velocity
2 NM 50,000 0 fpm. 0 Kts
10. Set the intruder type as ATCRBS.
11. Verify a target is annunciated on the GTS 8XX TAS/TCAS display at the correct bearing of
approximately 0 degree azimuth at 2 NM and co-altitude (read as 00 above a filled diamond
indicating proximate traffic).
12. Toggle intruder traffic to standby or off.
13. Reposition ramp test set and directional antenna to a starboard position of 90 degrees.
Page 3-18 GTS 8XX/GPA 65 Installation Manual
Revision 4TP 190-00587-00
14. Reengage the same intruder scenario as above.
15. Verify a target is annunciated on the GTS 8XX TAS/TCAS display at the correct bearing of
approximately 90 degree azimuth at 2 NM and co-altitude.
16. Toggle intruder traffic to standby or off.
17. Reposition ramp test set and directional antenna to an aft position of 180 degrees.
18. Reengage the same intruder scenario as above.
19. Verify a target is annunciated on the GTS 8XX TAS/TCAS display at the correct bearing of
approximately 180 degree azimuth at 2 NM and co-altitude.
20. Toggle intruder traffic to standby or off.
21. Reposition ramp test set and directional antenna to a port position of 270 degrees.
22. Reengage the same intruder scenario as above.
23. Verify a target is annunciated on the GTS 8XX TAS/TCAS display at the correct bearing of
approximately 270 degree azimuth at 2 NM and co-altitude.
24. Toggle intruder traffic to standby or off.
25. If the bearing is not as anticipated, recheck the antenna coaxial connections and verify the
correct antenna type is selected.
NOTE
If multiple targets are displayed during the antenna tests, recheck the antenna coaxial
connections.

4. Install a doubler plate to reinforce the aircraft skin as necessary.
5. Place the supplied O-ring, 251-00011-00, in the groove on the bottom surface of the antenna.
6. Mount the antenna to the airframe with the four supplied #8-32 stainless steel screws, 211-
60209-16. Washers and locking nuts (not provided, may be part of doubler plate) are required
to secure the antenna. Apply torque evenly across all mounting screws.
7. Ensure that the antenna base and aircraft skin are in continuous contact.
8. Fillet seal the antenna and gasket to the fuselage using a good quality electrical grade sealant,
MIL-S-8802B or equivalent. Run a bead of the sealant along the edge of the antenna where it
meets the exterior aircraft skin. Use caution to ensure that the antenna connector is not
contaminated with sealant. Seal the mounting screws with sealant.
9. Connect the four antenna cables ensuring each cable is connected to the correct antenna
connector. Each antenna connector and cable has a matching color band.
