Recommended Tools and Supplies:
- Any electric drill and a 9/16 inch drill bit
- A 24mm open end or adjustable wrench to tighten hex nut when deck mounting
- Any tool to help cable routing (e.g., flat dental pick, screwdriver, etc.)
- Grommet and silicone sealer (for cable routes)
- (Optional) Antenna Extension with 1"-14 threads
- (Optional) Any mounting bracket with 1"-14 threads
Installation Precautions and Tips:
- When selecting an antenna location, make sure the antenna is not enclosed by any metal material. If a metal fly bridge is to be used, the antenna must protrude at least 5 inches above the bridge’s top edge. Consider using an antenna extension to increase the height above the boat.
- Also, at the proposed site, verify that there is at least a 20-degree clearance from any metallic obstruction on all sides, as shown in figure 6 (on the next page).
- Prior to installation, turn off all audio systems and other electrical devices. Disconnect the (–) negative lead from the boat’s battery.
- At the installation site, locate and make a note of all fuel lines, cables, and electrical wiring. Use extreme caution when cutting or drilling in and around these areas. Always wear protective eye wear when using tools.
- When drilling fiberglass surfaces, use a small backup block of wood to help control splintering.
- As you plan the cable route, avoid running the cable through any component that may cause excessive chafing. Doing so may erode the jacket and break signal continuity. Also, avoid kinking, pinching, excessive bending, or twisting of the cable during a run.
- Do not trim the cable length. It is optimized for best signal reception. Coil and store any excess cable behind the Sirius receiver.
- Do not remove the connectors from the cables.
Installing the TERK SIRMarine Satellite Radio Antenna
Deck or Flat Surface Mounting:
- At the chosen site, drill a 9/16 inch mounting hole. For mounting surfaces thicker then 1/4 inch you will need to attach the supplied slotted extension adapter to the SIRMarine antenna. Simply route the 6 inch long antenna cable through the slot and thread the extension adapter onto the existing antenna shaft and tighten.
- Pass the TNC connector and the 6 inch antenna cable through the hole in the mounting surface.
- Install the lock washer and hex nut onto the antenna shaft and tighten securely assuring that the antenna is seated properly.
- Attach the 25 foot coax cable to the 6 inch antenna cable by connecting the TNC connectors securely. See figures 7 and 8 below.
Continue to the “Connecting To Your Sirius Radio” section on the next page.
Mast or Bracket Mounting: The Terk SIRMarine Satellite Radio Antenna is easy to install on any standard mast or brackets that have a 1”-14 thread.
- Attach the Threaded Flange Adapter to the SIRMarine by first passing the TNC connector on the 6 inch antenna cable lead through the adapter as shown in Figure 9 on the next page. Next thread the adapter on to the threaded extension of the SIRMarine and tighten securely. Note: do not use the supplied Slotted Threaded Adaptor in this application.
- Connect the TNC connector on the 6 inch antenna cable lead to the mating TNC connector on the 25 foot cable and tighten securely. The 25 foot cable can be routed through the provided access holes and grommet that are located on the mast or bracket. Since the SMB connector has a much smaller diameter it is recommended that you route this connector through any access hole necessary. Many masts have grommets that can be removed which makes it easier to route the cable through the access hole. The grommet can be placed over the SMB connector and put back in place for a neat install.
- Secure the SIRMarine antenna and adapter to the mast or bracket by tightening onto the 1”-14 thread securely. All mast and brackets should be installed on the boat per manufacturers specifications. If needed, adjust the tilt so that the antenna is perpendicular to the horizon.
Connecting to your Sirius Radio:
- Connect the SMB connector to the Sirius Satellite Receiver. Turn on the Sirius system and tune the radio to channel 184 (i.e., the preview channel) to verify that the antenna is properly installed. If there are any problems, review the installation steps and verify that each one was performed correctly. Also see Troubleshooting on the next page.
- After the system has been tested successfully, continue dressing the cable from the antenna to the receiver for best appearance and complete any remaining installation. Use cable tie wraps where needed to secure cables from flagging in the wind and catching on objects. Seal any holes in the bulkheads with a marine grade RTV or silicon adhesive.
Note: For additional help with cable routing, consult your local marine audio dealer.
