TRK-SR2 INSTALLATION GUIDE  
INTRODUCTION  
The Terk TRK-SR2 Roof-Mount Satellite Radio Antenna is a high-performance  
antenna designed specifically for XM Satellite Radio reception. It has dual-mode  
functionality, receiving simultaneous signals from satellites and terrestrial  
repeaters, to ensure continuous reception. The result is an antenna that offers all  
the benefits of satellite radio and complements the appearance of any vehicle.  
Its features include:  
Low-profile roof-mounted design  
Mounts to roof of vehicle via special acrylic foam adhesive pads that  
provide years of worry-free enjoyment, yet are removable if necessary  
Attached micro cables are designed to wrap around the rear window and  
to fold under rubber molding for an invisible wiring solution  
Tested and proven to Automotive Environmental Standards  
Shock- and vibration-proof design  
Safe for low-clearance conditions, including car washes  
The TRK-SR2 is easy to install on most vehicles. The package includes all the  
necessary mounting hardware, as well as color-coded cable connectors to  
ensure complete compatibility with all XM receivers. Remember to save your  
sales receipt and this guide so both are available for future reference.  
NOTE: To achieve best XM Satellite Radio reception, also refer to the XM radio’s  
owner’s manual.

NOTE: The TRK-SR2 can be used on a convertible with a removable metal roof as  
long as the top is off. Using the roof may cause interference and degraded reception.

RECOMMENDED TOOLS AND SUPPLIES  
Although not necessary, the following tools and supplies may aid in installation:  
Any tool to help cable routing (e.g., flat dental pick, screwdriver, etc.)  
Lubricant (e.g., light machine oil to aid cable routing through old molding)  
Cable tie wraps and adhesive mounting bases (to manage cable routing)  
Tape measure and level (for positioning the antenna)  
INSTALLATION PRECAUTIONS AND TIPS  
When selecting an antenna location for the TRK-SR2, make sure the  
proposed site meets the following conditions:  
a. The selected site must have a conductive surface area (e.g., metal or  
aluminum roof) of at least 2-14 square feet and be 6 inches from  
rear window molding.  
b. Line of sight to satellites must not blocked by any metal obstructions  
(e.g., crossbars from a roof rack).  
c. Choose the highest possible location on the vehicles roof that satisfies  
the above conditions and is as flat as possible.  
Although a center position on a roof is the most aesthetically pleasing, if  
there is an obstruction (e.g., skid ribs, protruding brake light on roof line,  
etc.) consider offsetting the TRK-SR2 from the center. If this doesnt work,  
use the Terk TRK-SR1 Glass-Mount Satellite Radio Antenna instead.

Installation

TRK-SR2 INSTALLATION GUIDE  
If the vehicle is equipped with a roof rack, adjust the crossbar so its at  
least 6 inches away from the TRK-SR2.  
If the vehicle is equipped with a metal sunroof (e.g., Mazda 626), which  
opens to the outside, allow a minimum distance of 6 inches from the edge  
of the open sunroof to the TRK-SR2. If this is not possible, use the Terk  
TRK-SR1 Glass-Mount Satellite Radio Antenna instead.  
NOTE: A glass sunroof does not require this minimum mounting distance, since  
the glass does not block satellite signals nor degrade reception.  
Before mounting the TRK-SR2, make sure the vehicles roof is above 60 °F,  
non-condensing, and dry. This will also allow the molding to soften up.  
At a selected antenna site, survey the planned cable route and look for any  
blocked passages. Consider alternate routes to find the best available path.  
NOTE: Take advantage of any existing cable channels (e.g., brake light  
opening ) or wiring conduits to route the cables.  
Avoid running cables through components that may cause excessive chafing.  
Doing so may erode the jacket and break signal continuity. Also, avoid  
kinking, pinching, or twisting a cable during a run.  
When routing the cable through small openings, consider removing the  
plastic cases and inserts from connectors (see Figure 12 on page 9).  
For convertibles with composite trunk lids, attach an aluminum foil  
ground planeof at least 2-14 square feet, centered under the antenna  
module, between the lid and liner.  
When pressing the TRK-SR2 onto the vehicles roof, apply an initial  
contact force of 15 to 20 PSI (i.e., steady and firm finger-tip pressure) for  
60 seconds. Allow 20 minutes for the self-adhesive backing to set before  
driving the vehicle.  
After installation, avoid running the vehicle through a car wash for 72 hours.  
INSTALLING THE TRK-SR2  
1. At the selected site, use an enclosed Cleaning Towelette to clean the  
installation area on the vehicles roof.  
NOTE: For additional cleaning solution, only use isopropyl alcohol. Do not use  
any commercial glass cleaners.  
2. Peel off both protective backings from the cable cover and antenna module.  
Lightly position the end of the cable cover at the rear window molding, as  
shown in Figure 9 on the next page.  
NOTE: The end flap should extend over the molding (see Figure 9).

3. Continue placing the molding down on the roof, working forward towards the  
antenna module. Examine the placement and make any desired adjustments.  
4. Using steady pressure, firmly press the TRK-SR2 (including cable cover)  
down for a minimum of 60 seconds to secure adhesion to the roof.  
5. Push the cables under the rear window molding and route them to the XM  
receiver, as shown in Figure 10 below. The cables can be routed separately (as  
shown) or together along a single route.

6. If the XM system is not already installed, temporarily connect power and  
ground to the system. Connect the TRK-SR2 to your XM receiver, as directed  
by the receivers manufacturer (see Figure 11 below).

7. Turn on the XM system and tune to different XM channels. If there are any  
problems, review the installation steps and verify that each one was  
performed correctly.Also see Troubleshooting on the next page.  
8. After the system has been tested successfully, route the cable from the  
antenna to the receiver for best appearance and complete the remaining  
system installation.  
NOTE: For additional help with cable routing, consult your local mobile  
audio dealer.
