About Installation
Installation of automotive audio components can require extensive experience with a variety of
mechanical and electrical procedures. Although the instructions in this guide explain how to install
the TERK SIR4 Truck Satellite Radio Antenna in a general sense, they do not show the exact
installation methods for your particular vehicle.
NOTE: Installation of the TERK SIR4 Truck Satellite Radio Antenna may cause mirror vibration and
hamper drivers rear-view image.
IMPORTANT: If you are not comfortable performing a complex installation, ask your local
mobile audio dealer about professional installation options.

accommodating the U-Bracket clamp style mounting.
Features
• Aerodynamic Antenna Assembly Design
• 21 feet of RG174 Coax Cable with Right-Angle SMB connector
• Ground Plane Independent Design
• Field Replaceable Sub-Assembly Components
• Robust Antenna Design to withstand Long Haul Truck Vibration Environments
• High Performance meets Sirius Satellite Radio Specifications

SIR4-Truck Satellite Radio Antenna

Applications
The TERK SIR4-Truck Satellite Radio Antenna is designed with multiple install options. When using
the mirror mount bracket it can be installed on the driver side or passenger side rear view mirror
of a truck or RV as shown in Figure 1. When using the included U-bracket the antenna can be
mounted on the truck’s air dam shield, flap, or any flat surface that accommodates the U-bracket
clamp style mounting.
Figure 1. The TERK SIR4-Truck Satellite Radio Antenna is shown installed on the
horizontal driver’s side mirror support of a long-haul truck.

Installation
Installation Tips
• The cable length as supplied is part of the electrical circuit of the antenna. DO NOT ALTER THE
CABLE LENGTH. The cable must not be cut, spliced or altered in any manner, as satellite receiver
reception will be adversely affected. Excess cable may be stored where it will not be damaged.
• Care must be taken during installation to avoid nicks, cuts or damage to the cable and cable
jacket. Once damaged the cable cannot be repaired and must be replaced.
• The connector should not be removed for routing purposes. It cannot be repaired or replaced
once removed in the field. If damaged you will need to replace the entire cable assembly.
•To ensure that water does not seep into the connector connecting the cable to the Antenna
Assembly make sure the rubber boot is tightly secured onto the Antenna Assembly.
• Cable ties may be required depending on the desired installation. These items are not included in
the packaging.
•Select a mounting location that enables the antenna to have a clear and unobstructed view (no
impediments/blockages below 25 degrees from horizontal). The truck cab or truck trailer should
not block the view of the antenna.
• To decrease interference from other antennas mounted on the vehicle, place this antenna on the
opposite side of the truck from any HAM or CB radios.

Mirror Mount Installation
NOTE: The mounts supplied may not fit on all model year and make truck mirrors. If your rig does
not have the chrome pipe type mirror bars you will need to use the Air Dam Shield mounting
method or flat surface mounting method.
1. Insert the Antenna Assembly into the Mirror Mount Clamp hole. See Figure 2 on page 5.
2. On the bottom side of the Mirror Mount Clamp A place the 3/4” Ext. Tooth Lock Washer on the
Antenna Assembly Shaft.
3. Now place the 3/4”-16 Hex Nut onto the shaft securing the nut with a 3/4” Open-End Wrench.
4. Using a torque wrench tighten to 10.5ft-lbs. (126 in-lbs.) using the appropriate torque wrench
adapter (1-1/8”).
5. Select the highest location on the truck mirror to mount the satellite radio antenna without
obstruction.
6. Take the four M6XP1.0 Hex Screws and insert them through the four holes in Mirror Clamp A.
7. Take Mirror Mount Clamp B and insert them onto the four M6XP1.0 Hex Screws and Mirror
Mount Clamp A.
8. Now place the four M6 Lock Washers onto the M6XP1.0 Hex Screws.
9. Now place the four M6 Washers onto the M6XP1.0 Hex Screws.
10. Now use the M6XP1.0 Hex Nuts and hand tighten all four onto the M6XP1.0 Hex Screws.
11. Using the torque wrench torque the M6XP1.0 Hex Nuts to 15 in-lbs.

Mirror Mount Installation Continued
12. Take the cable connector (180 degree connector) not the Right-Angle SMB Connector and
hand tighten over the connector on the bottom side of the Antenna Assembly. See Figure 6.
13. Using the 5/16” open-end wrench, tighten the cable connector on the Antenna Assembly
connector.
14. Place the rubber boot over the end of the Antenna Assembly shaft after the cable connector
has been tighten. See Figure 6.
15. The next step is routing the cable from the Antenna Assembly to the satellite radio receiver
inside the truck cab. Since every truck cab is slightly different this is only a guide line to
follow and your cable routing maybe different.
16. Route the cable through the vent window of the truck cab. Again DO NOT BEND the cable at
90 degree angles as this will break the coax center conductor causing the satellite receiver
not to receive the satellite radio broadcast. See Figure 4.
17. If you have an access hole and do not want the cable routing through the window vent
route the cable through this hole. See Figure 5.
18. Connector the Right-Angle SMB connector to the satellite radio receiver.

Air Dam Shield Mount Installation
NOTE: The mounts supplied may not fit on all model year and make truck mirrors. If your rig does
not have the chrome pipe type mirror bars you will need to use the Air Dam Shield mounting
method or flat surface mounting method.
1. Insert the Antenna Assembly into the Air Dam Shield Clamp D hole. See Figure 7.
2. On the bottom side of the Air Dam Shield Clamp D place the 3/4” Ext. Tooth Lock Washer on the
Antenna Assembly Shaft.
3. Now place the 3/4”-16 Hex Nut onto the shaft securing the nut with a 3/4” Open-End Wrench.
4. Using a torque wrench tighten to 10.5ft-lbs. (126 in-lbs.) using the appropriate torque wrench
adapter (1-1/8”).
5. Select the highest location on the truck mirror to mount the satellite radio antenna without
obstruction. See Figure 7a.
6. Place the 3/8” Int./Ext. Lock Washer onto the U-Bracket screw.
7. Assemble the U-Bracket into the Air Dam Shield Clamp D hole. See Figure 7.
8. Place the 3/8” Split Lock Washer onto the U-Bracket screw.
9. Hand Tighten the 3/8”-16 Hex Nut onto the U-Bracket screw. Using the appropriate torque
wrench and adapters (9/16” size hex or open-end), torque 3/8” hex nut to 12 ft-lbs.

Air Dam Shield Mount Installation Continued
10. Install antenna to Air Dam Shield of truck, See Figure 8.
11. Loosen two screws and two hex nuts in U-Bracket assembly. Note: Installation on tubular sur-
face is NOT recommended. Insert Air Dam Shield edge between the U-Bracket Assembly and
Clamp feet. See Figure 9.
12. Tighten clamp screws on U-Bracket Assembly evenly up against the Air Dam Shield to
15 ft-lbs. using the appropriate torque wrench and adapters (1/2” size, hex or open-end
wrench). IMPORTANT: Assure two 5/16” Hex Nuts are not tight at this step.
13. Tighten two 5/16”-18 Hex Nuts securely up against clamp bracket, See Figure 9.
14. Using the appropriate torque wrench and adapters (1/2” size, hex or open-end wrench) torque
5/16-18 Hex Nuts to 4 ft-lbs. (48 in-lbs.).
15. Loosen the 3/8”-16 Hex Nut and pivot antenna until true vertical position is achieved. Re-torque
3/8”-16 Hex Nuts to 12 ft-lbs.
16. Take the cable connector (180 degree connector) NOT the Right-Angle SMB Connector and
hand tighten over the connector on the bottom side of the Antenna Assembly. See Figure 10.
17. Using the 5/16” open-end wrench, tighten the cable connector on the Antenna Assembly
connector.
18. Place the rubber boot over the end of the Antenna Assembly shaft after the cable connector has
been tighten. See Figure 10
19. Route cable into truck cab and connect to satellite receiver. Verify you have satellite broadcast.
