Setup: Starlink Flat High Performance Kit Setup Guide

Content

Overview

The Flat High Performance Kit is a Starlink satellite internet setup designed for stable, low-profile installation on flat surfaces, including vehicles, boats, RVs, and other locations with a clear view of the sky. It is built for users who want a more secure mounting solution and a cleaner install than a temporary placement.

This guide covers the included hardware, mounting approach, safety precautions, and the step-by-step installation process for the dish and power supply.

Detailed description

The Flat High Performance Kit centers around the Starlink dish, a wedge mount, a power supply, and a separate mount for the power supply. The wedge mount positions the dish at a fixed angle so it can maintain a clear sky view while staying firmly attached to a flat surface.

The kit is designed around two linked installation areas. First, the dish is fastened to the wedge mount using shoulder bolts and socket head bolts. Second, the power supply is fixed to a wall or other suitable surface and connected with the included Starlink, AC, and Ethernet cables. The dish cable locks into place with a latch, helping prevent accidental loosening after installation.

The included hardware supports a secure, sealed install when used with the supplied silicone sealant and thread locker. This makes the Flat High Performance Kit well suited to outdoor and mobile use where vibration, movement, and weather exposure are concerns.

Safety

Use caution during installation, especially if mounting on a vehicle or vessel. The dish and mount must be attached to a strong, level surface that can support the system safely and still give the antenna a clear view of the sky.

Do not proceed with installation if any part of the process feels unsafe or unfamiliar. A qualified professional should handle the job when needed. Poor mounting can lead to damage, injury, or equipment failure.

The mount is not intended for high-wind events such as hurricanes or tornadoes, so tethering is required to reduce the risk of failure in extreme weather. The installation should also comply with local road or maritime rules when used on a moving vehicle or vessel.

When drilling, wear eye, hand, and face protection. Avoid electrical wiring, studs, and water lines, since hitting any of them can cause serious damage or injury. Drill at a slight downward angle from inside to outside, and seal the openings thoroughly to help prevent leaks and insect intrusion.

Setup and operation

What to do before mounting

Start by downloading the Starlink app and using the obstruction tool to choose a location with a wide, unobstructed view of the sky. Trees, poles, roofs, and similar obstructions can interrupt service as satellites move overhead.

Install the wedge mount

Mark the four mounting holes on the wedge mount and drill pilot holes with a 6.5 mm drill bit. Clean away debris and remove any burrs around the holes before fastening the mount.

Place the rubber washers over the holes, position the mount, and apply silicone sealant to the machine screw threads. Insert the screws through the mount and pre-drilled holes, then secure each one with a washer and nut. Tighten to snug plus a quarter turn, but do not overtighten.

Attach the dish

Install the shoulder bolts into the threaded holes near the cable port and tighten them by hand. Align those bolts with the keyway on the underside of the mount, then push the dish down and slide it forward until it locks into place.

After the dish is seated, fully tighten the shoulder bolts. Install the remaining socket head bolts with thread locker in the two open holes. Use the correct 12.7 mm (0.5 in) bolts only, since longer bolts can damage the dish.

Connect power and data

Plug the Starlink cable into the port on the bottom of the dish and make sure it is fully inserted. Push the latch into the locked position until it clicks, which helps confirm a secure connection.

If the kit is being used with a Starlink router, continue through the app-based setup process. If a compatible third-party router is being used, follow that router’s setup steps after connecting the Ethernet cable.

Install the power supply mount

Remove the power supply from its mount and choose a location no more than 1.8 m from the power source. Mark the two pilot holes, drill them with an 8 mm bit, and insert the wall anchors until flush.

Secure the mount to the wall, then connect the Starlink, AC, and Ethernet cables to the power supply. Slide the power supply into the mount until the top clip snaps into place. Finish by routing the Ethernet cable to the router location and plugging in the router and power supply.

Faqs

How do I choose the best mounting location for the Flat High Performance Kit?

Pick a location with a clear view of the sky so the dish can maintain a stable connection as satellites move overhead. Trees, poles, roofs, and other obstructions can interrupt service and reduce performance. Before drilling, use the Starlink app’s obstruction tool to confirm the spot is suitable. For moving vehicles or vessels, the mount must be on a firm, structurally sound, horizontal surface and positioned away from other equipment that could block the sky view.

What should I check before drilling holes for the wedge mount?

Before drilling, mark the four mounting holes carefully and confirm the surface can support the hardware. The included machine screws are meant for mounting surfaces up to 11.44 mm thick. Drill the pilot holes with the recommended 6.5 mm bit, then remove any burrs and debris around the openings. It is also important to avoid studs, electrical wiring, and water lines. A slightly downward drilling angle from inside to outside helps reduce water intrusion.

How do I properly secure the Flat High Performance dish to the mount?

After placing the shoulder bolts into the threaded holes near the cable port, align them with the keyway on the underside of the mount. Push the dish down and slide it forward until it locks in place. Then fully tighten the shoulder bolts. To finish securing the dish, install the remaining socket head bolts with thread locker and tighten them to snug plus a quarter turn. Do not overtighten, and make sure the shorter specified bolts are used.

Why is silicone sealant used during Flat High Performance Kit installation?

Silicone sealant helps protect the mounting point from moisture after drilling through an exterior surface. The guide calls for sealant on the machine screw threads before inserting them through the mount and pre-drilled holes. This extra step helps reduce the chance of water or bug intrusion around the penetration. For the best result, make sure the surface is clean, the holes are free of debris, and the sealant is applied generously where instructed.

How do I connect the Starlink cable correctly on the Flat High Performance Kit?

Plug the Starlink cable into the port on the bottom of the dish and make sure it is fully seated. Once inserted, push the latch into the locked position until you hear or feel a click. A loose connection can cause setup problems or intermittent service. After the dish is mounted and cabled, follow the app-based installation flow if you are using a Starlink router. With a compatible third-party router, use that router’s setup steps instead.

Where should the power supply mount be installed?

The power supply mount should be placed no more than 1.8 m from your power source for a practical cable run. Mark the two pilot holes, drill them with the 8 mm bit, and insert the included wall anchors until flush. After attaching the mount to the wall, slide the power supply into place until the top clip snaps securely. Then connect the Starlink, AC, and Ethernet cables before routing the Ethernet cable to your router location.

What safety precautions should I follow during installation?

Wear eye, hand, and face protection when drilling, and work carefully around walls, roofs, and vehicle surfaces. Avoid drilling into studs, electrical wiring, and water lines because that can cause serious injury, fire, or property damage. If any part of the installation feels uncomfortable or uncertain, the guide advises using a professional installer. Extra caution is required for vehicle or vessel setups, especially because the mount must be firmly secured and the installation must meet local regulations.

Can the Flat High Performance Kit be used in high winds or on moving vehicles?

The mount is not designed for high winds, including hurricane or tornado conditions, so tethering should be used to reduce the risk of failure during an unexpected wind event. For moving vehicles or vessels, the dish must be installed on a stable, horizontal surface that is structurally sound and able to hold the mount securely. If the structure cannot be properly secured, do not install it there. Poor installation can create serious safety hazards.
