3 GPS/SIRIUSXM® ANTENNA INSTALLATION This section contains general information as well as installation information for GPS and SiriusXM antennas. Use this section to mount the GPS/SiriusXM antenna(s). In an installation with multiple Garmin Device units, each Garmin Device can be configured to use its own internal GPS receiver, or to receive GPS data transmitted by another Garmin Device.
3.1 Garmin Antennas If using a Garmin GA 26C or GA 26XM, refer to the accompanying installation instructions (190-00082-00 or 190-00522-03). For GA 55/55A, or GA 56 or GA 57X antennas, refer to this section and the outline and installation drawings beginning with Figure C-1. Garmin recommends the antennas shown in Table 3-1. However, any equivalent GPS or SiriusXM® antenna that meets the specifications listed in Table 3-2 and Table 3-3 should work with the system.
Table 3-3 SiriusXM® Satellite Radio Antenna Minimum Requirements Characteristics Frequency Range Specifications 2332.5 to 2345 MHz Gain (Typical) 24 dB* Noise Figure <1.2 dB Nominal Output Impedance 50 ohms Supply Voltage Supply Current (maximum) 55 mA -50 to +85° C AF T Operating Temperature Gain 3.6 to 5.5 VDC *For each 1 dB gain over 24 dB, add 1 dB of attenuation into the antenna cable path between the antenna and the Garmin Device.
3.2.2 GPS/SiriusXM® Antenna Mounting Location The GPS antenna is a key element in the overall system performance and integrity for a GPS navigation system. The mounting location, geometry, and surroundings of the antenna can affect the system performance and/or availability. The following guidance provides information to aid the installer in ensuring that the optimum location is selected for the installation of the GPS antenna.
AF T Figure 3-1 shows the recommended placement of antennas. D R Add antenna placement figure Figure 3-1 Recommended Antenna Placement 190-00303-91 Rev.
3.2.3 Buried Antenna (below the skin covering or glareshield) Mounting There are potential performance issues related to buried antennas that the kit builder/installer should be aware of prior to electing to install a buried antenna. See also Section 3.5.3, Non-structural Installation to Glareshield. • • Some gain of the antenna may be lost as the signal needs to penetrate through the skin of the aircraft.
AF T Mounting the antenna under the glare shield (Figure 3-3) is a good option for SiriusXM® – FIS antennas, although it is not typically the best option for a GPS antenna. This location results in the aft fuselage shading the antenna.

B.1.2 Shield Termination Technique – Method A.1 (Standard) NOTE For the following steps please refer to the drawings showing the installation of a Jackscrew Backshell. AF T 1. The appropriate number of Jackscrew Backshells will be included in the particular LRU connector kit. Figure to be added Figure B-2 Method A.
3. Connect a Flat Braid (item 4) to the shield exposed through the window of the prepared cable assembly (item 2) from step 2. The Flat Braid should go out the front of the termination towards the connector. It is not permitted to exit the rear of the termination and loop back towards the connector (Figure B-2). Make this connection using an approved shield termination technique. NOTE FAA AC 43.
Secondary Method: Solder a Flat Braid (item 4) to the shield exposed through the window of the prepared cable assembly (item 2). Ensure a solid electrical connection through the use of acceptable soldering practices. Use care to avoid applying excessive heat that burns through the insulation of the center conductors and shorts the shield to the signal wire. Slide a minimum 0.75 inches of Teflon heat shrinkable tubing (item 3) onto the prepared wire assembly and shrink using a heat gun.
6. Insert newly crimped pins and wires into the appropriate connector housing location as specified by the installation wiring diagrams. 7. Cut the Flat Braid (item 4) to a length that, with the addition of a ring terminal, will reach one of the tapped holes of the Jackscrew backshell (item 1) (Figure B-1). An appropriate amount of excess length without looping should be given to the Flat Braid (item 4) to allow it to freely move with the wire bundle.
B.1.3 Shield Termination Technique - Method A.2 (Daisy Chain) In rare situations where more braids need to be terminated for a connector than three per ring terminal it is allowable to daisy chain a maximum of two shields together before coming to the ring terminal (Figure B-4). All other restrictions and instructions for the shield termination technique set forth for Method A.1 are still applicable. NOTE AF T The maximum length of the combined braids should be approximately 4 inches.
2. Steps 3 and 4 are replaced by the following: At the end of the shielded cable (item 2), strip “Quick Term Min” to “Quick Term Max” (Table B-4) length of the jacket to expose the shield. Next trim the shield so that at most 0.35 inches remains extending beyond the insulating jacket. Fold this remaining shield back over the jacket. AF T Connect a Flat Braid (item 4) to the folded back shield of the prepared cable assembly. The flat braid should go out the front of the termination towards the connector.
Secondary Method: Solder a Flat Braid (item 4) to the folded back shield on the prepared cable assembly (item 2). Ensure a solid electrical connection through the use of acceptable soldering practices. Use care to avoid applying excessive heat that burns through the insulation of the center conductors and shorts the shield to the signal wire. Slide a minimum of 0.75 inches of Teflon heat shrinkable tubing (item 3) onto the prepared wire assembly and shrink using a heat gun.
B.1.5 Shield Termination-Method B.2 (Daisy Chain-Quick Term) In rare situations where more braids need to be terminated for a connector than three per ring terminal it is allowable to daisy chain a maximum of two shields together before coming to the ring terminal (Figure B-6). All other restrictions and instructions for the shield termination technique set forth for Method B.1 are still applicable. NOTE AF T The maximum length of the combined braids should be approximately 4 inches.
B.1.6 Daisy Chain between Methods A and B In rare situations where more braids need to be terminated for a connector than three per ring terminal and a mixture of Methods A and B have been used, it is allowable to daisy chain a maximum of two shields together from a Method A termination to a Method B (Figure B-7). All other restrictions and instructions for the shield termination technique set forth for Method A and B are still applicable.
B.1.8 Splicing Signal Wires NOTE Figure B-8 illustrates that a splice must be made within a 3 inch window from outside the edge of clamp to the end of the 3 inch max mark. WARNING AF T Keep the splice out of the backshell for pin extraction, and outside of the strain relief to avoid preloading. Figure B-8 shows a two wire splice, but a maximum of three wires can be spliced. If a third wire is spliced, it is located out front of splice along with signal wire going to pin.
