4. Setup and Installation
Follow these steps for proper installation of your Scanstrut APT-150-SL-01 PowerTower and Starlink antenna:
- Select Mounting Location: Choose a suitable, flat, and structurally sound location on your powerboat's roof, T-top, flybridge, or radar arch. Ensure the location provides clear line-of-sight for the Starlink antenna and allows for proper cable routing.
- Prepare Mounting Surface: Clean the mounting surface thoroughly. Mark the drilling points using the PowerTower base as a template.
- Drill Mounting Holes: Carefully drill holes as marked. Ensure appropriate drill bit size for your fasteners (not included).
- Secure PowerTower: Position the PowerTower over the drilled holes. Use appropriate marine-grade fasteners (bolts, washers, nuts) to secure the PowerTower firmly to the boat structure. Tighten all fasteners evenly to prevent stress points.
- Attach Starlink Antenna: Align the Starlink High-Performance antenna with the pre-drilled mounting holes on the top plate of the PowerTower. Secure the Starlink antenna using its provided fasteners. The PowerTower is designed for direct attachment without modification.
- Route Cables: Guide the Starlink cable through the integrated Scanstrut cable seal located within the PowerTower. This seal ensures a waterproof entry point for the cable without requiring the Starlink connector to be cut. Ensure the cable is routed safely, away from sharp edges or moving parts, and secured to prevent chafing or damage.
- Final Inspection: After installation, visually inspect all connections and fasteners to ensure they are secure. Verify that the Starlink antenna is stable and positioned correctly at the 8-degree angle.

5. Operating Instructions
The Scanstrut APT-150-SL-01 PowerTower is a passive mounting solution and requires no operational input once correctly installed. Its function is to provide a stable, secure, and optimally angled platform for your Starlink High-Performance antenna. Ensure the Starlink antenna is correctly seated and all cables are securely routed and protected.
6. Maintenance
Regular maintenance will help preserve the appearance and functionality of your PowerTower:
- Cleaning: Periodically clean the PowerTower with fresh water and a mild, non-abrasive soap. Rinse thoroughly to remove any salt residue. Avoid using harsh chemicals or abrasive cleaning tools that could damage the paint finish.
- Inspection: Regularly inspect the PowerTower for any signs of corrosion, damage, or loose fasteners. Pay close attention to the mounting points and the cable seal area.
- Fastener Check: Annually, or after any significant impact or rough weather, check and re-tighten all mounting fasteners to ensure the PowerTower remains securely attached to your vessel.
- Cable Seal: Ensure the integrated cable seal remains intact and free from cracks or degradation to maintain its waterproof integrity.
7. Troubleshooting
Most issues related to the PowerTower are installation-dependent. Consider the following if you encounter problems:
- Starlink Connectivity Issues: If your Starlink experiences intermittent or poor connectivity, first verify that there are no new obstructions (e.g., new equipment, sails, rigging) blocking the antenna's field of view. Confirm the antenna is still securely mounted at the intended 8-degree angle.
- Loose PowerTower: If the PowerTower feels loose or unstable, immediately check all mounting fasteners. Re-tighten them according to the installation instructions. Do not operate your vessel with a loose mount.
- Water Ingress: If you suspect water is entering through the cable entry point, inspect the integrated Scanstrut cable seal for damage or improper installation. Ensure the cable is correctly seated within the seal.
- Corrosion: While designed for marine environments, prolonged exposure to harsh conditions without proper maintenance can lead to corrosion. Refer to the maintenance section for cleaning and inspection procedures.
