Key Considerations for a Successful Install

  1. Minimize Obstructions: Each Starlink should have a clear view of the sky 20° elevation above the horizon, 360° around the azimuth. You may need to raise the antennas on a pole/pedestal to get a clear view of the sky & good service. If you have obstructions > 20° elevation in any direction, the connection may be occasionally interrupted.
  2. Orientation of the Mounts: The mounts are tilted 8° to facilitate water runoff. Ideally, the antennas should be tilted in the direction with the fewest obstructions. Be sure to use a removable thread locker on all threaded fasteners.
  3. Orientation of the Dish & Power Supply Unit: Dish & PSU should be set up so that connectors are facing down or to the side. This is to avoid water collecting or sitting around the seal.
  4. Cables: The maximum distance from the dish to the power supply is 25m (75'). The maximum total distance from the dish to the network equipment (passing through the power supply) is 100m (300'). The minimum bend radius of the cable is 5cm (2"). Sharp kinks in the ethernet cables can lower the throughput speed. The cables are not reversible. The connector on the end of the cable is specific to the device to which it connects.
  5. Power: Starlink power supply input range 100-240V - 6.3A 50 - 60 Hz. Recommend using UPS-backed power supply to maintain internet connection through power dips and short power outages. The Starlink Power Supply supplies power to the dish and allows the data to pass through. For DC power sources, use a Pure Sine Wave inverter rated minimum 500W.
  6. Network: Once the dish connects to the Starlink network, it allows the local device to request and be assigned an IP address. This IP will default to a CGNAT IP address unless the "Public IP" option is configured in the dashboard. More information on IP addresses can be found here
  7. Multiple Starlinks: If installing multiple Starlinks in one location, the minimum separation distance from the mount center to mount center should be 0.9 meters. If multiple antennas are installed in close proximity, they should tilt away from each other. A third-party router can be used to connect the Starlinks together into one network and provide load balancing, traffic shaping, failover, and other advanced capabilities.
  8. Support: It may take up to 20 minutes for Starlink to connect to the network. If you are having issues with setup, review the guidance in the Troubleshooting and Setup sections in Support. https://support.starlink.com/

Prepare for Install

Starlink App

Download the Starlink app first. The app will help you find an unobstructed install location, manage your account, test your connection, and browse the shop.

Select a Location

Find an Unobstructed Location

Starlink must be 100% unobstructed for best performance. Even small obstructions in the field of view will have a negative impact on the quality of the connection, including intermittent outages, dropped packets or sessions, and a reduction in overall average bandwidth capacity.

Each dish should have clear view of the sky from around 20° elevation (above the horizon), with a full 360° azimuth (rotation). If there are obstructions to the field of view, multiple dishes can be used, and load balanced with a 3rd party router. However, any dish with obstructions will result in lower than the rated performance (i.e. bandwidth throughput) from that dish. It is of utmost importance to install in a location with a clear view of the sky.

The wedge mount will tilt the dish such that the field of view is 12° at the lower side of the dish, and 28° at the upper side, and roughly 20° on the remaining two sides. If you are installing in an area with minor obstructions, it would be best to tilt the dish away from those obstructions.

Customers have been successful installing Starlink on masts, railings, elevated posts, and roofs, since the dishes are less likely to be obstructed and are better protected from salt spray.

If your Starlink will not be the tallest object in sight at the install location, be sure to use the Starlink app to ensure no obstructions such as masts, antennas, or other structures will interrupt your service.

Follow these additional guidelines for choosing your best install location:

  • Do not install next to a wall or other structure
  • Do not install under a covered outdoor area
  • Consider an elevated install (for example, on a pedestal, post, or rooftop) as the height improves the chances of clearing nearby obstructions

Use the app to be sure you are assessing obstructions accurately.

Using the Obstructions Tool in the App

  1. On the home page of the Starlink App, you'll see a button that says "FIND AN INSTALL LOCATION" which will open the obstructions tool.
  2. Once you're in the obstructions tool, follow the on-screen steps to scan the sky for obstructions at your install location.
  3. Select your Starlink hardware. This is needed to ensure the app is scanning the sky for the proper field of view.
  4. Be sure to place the phone at the exact location and height of your planned dish mounting location.

Hardware Details

Ingress Protection (IP) Rating

The Starlink dish and power supply are water jet and dust resistant and has been shown to survive for long durations (>6 months) in sustained corrosive marine environments (5% NaCl which is standard per ASTM). The Starlink WiFi router is designed for indoor use and is dust and splash resistant. More details on the hardware are available here.

Sealing Cable Connections

If your cable connection is exposed to significant amounts of water, we recommend using a sealant to prevent water damage. Only non-setting sealant, like dielectric grease, should be used around the seal.

No RTV should be placed on the seal, nor on the surface that interfaces with the seal, nor on the metal part of the connector. Once the cable has been fully inserted, then Dow 737 RTV can be used on the very outside of the socket/plug interface to provide additional waterproofing.

Cable Details

The Starlink cables are not reversible. In other words, the connector on the end of the cable is specific to the device it connects to. For example, be sure to route the cable with the dish end of the cable at the location of the dish, etc.

There is a MAXIMUM distance of 25 meters from the dish to the PSU. This is due to the voltage requirements at the dish. Do not attempt to extend the cable beyond 25 meters. We do not recommend cutting and splicing this cable. The total length from the dish to the network equipment is 100 meters.

The cables are manufactured to the following standards:

Installation Instructions

1. Mount the Dish

Maritime & Mobility applications are best served by the Flat High Performance Starlink (spec sheet here). For most applications, we recommend mounting using our Wedge Mount to install the dish at a slight angle. This encourages rain water to run off the dish to prevent accumulation of droplets which would impact performance by blocking the beams to/from the satellite. However, for higher-speed vehicles a flat (horizontal) installation is acceptable to minimize drag.

Be sure to use removable thread locker (for example Loctite 222) on all threaded fasteners, to prevent the faster from backing out due to vibration.

Starlink Wedge Mount Details

If you plan to use the Starlink Wedge Mount, please keep the following in mind:

  • The mount should be installed on a structurally sound, horizontal surface.
  • Use appropriate installation hardware for the installation surface.
  • Orient the mount so the lower end of the dish has the cable connection and points forwards when in motion.
  • Do not allow salt water to collect around your Starlink. Periodically check the sealant on your fasteners and rinse with fresh water.

For detailed instructions, reference the Wedge Mount Install Guide.

Other mounting solutions

  • Starlink Pole Mount Adapter for Flat HP: for mounting on the end of a pole or mast.
  • Starlink Cruise Mount: similar to the Wedge mount but provides additional space below the Starlink to mount the power supply unit (available upon request).
  • Third-party pedestal mounts (for example this product made by SeaView).
  • Beam clamps or U-bolts can be used to install the wedge mount on a railing. This will require drilling into the mount.

2. Mount the Power Supply

Mount the power supply using the supplied mount. The power supply is rated IP56. However, to prevent water pooling around the connectors, the power supply should be mounted with the connectors at the bottom or the side of the enclosure.

The power supply dissipates approximately 20W of heat and should be mounted in a well-ventilated environment. If it is enclosed be sure to provide a mechanism for the heat to escape. If the power supply over heats it will shut off resulting in a loss of internet connection.

3. Connect the Dish

Connect the Starlink dish to power supply with the provided Starlink Cable.

The Flat High Performance kit includes an 8 meter cable. If 8 meters is not long enough for your installation, you can purchase a 25m cable in the Starlink Shop. Due to power requirements, the cable from the power supply to the dish can not be extended beyond 25m.

4. Connect the Power

Use the power cable to connect the power supply and the router (if in use) to a power source supplying AC voltage.

It is recommended to power the Starlink and any downstream router from a power source protected by an Uninterruptable Power Supply (UPS) to protect the Starlink from power spikes and surges and to provide continuous power to the Starlink through minor dips (brownouts) or short power outages.

5. Connect the Network

OPTION 1: Use the included Starlink WiFi router.

  1. Use the Starlink Router cable to connect the power supply to the Starlink WiFi router.
  2. Stand close to the router, open the Starlink app, and tap ‘Start Setup’.
    1. This will guide you through the setup and prompt with WiFi configuration steps like setting a Network name and password.
    2. No Starlink app? Find and connect to the STARLINK network in your device’s WiFi settings.
  3. Confirm you are connected by navigating to a website, watching a video, or running a speed test from the app while connected to Starlink. You will see an ONLINE status on the main screen of the app.
  4. We recommend using the Starlink router for initial setup confirmation. See the WiFi section for additional guidance

OPTION 2: Connect directly to a device or third-party router

  1. Use the Starlink Ethernet cable to connect the power supply directly to ethernet port of a device or to the WAN port of a third-party router.
  2. If the ethernet connection cable is not long enough, we suggest terminating or patching the cable. If the connection is outdoors, be sure to use a weatherproof connection. This cable from the power supply to your network is standard ethernet and can be extended up to 100m.
  3. Connect the RJ-45 on the end of the ethernet cable to a computer or third-party router (or other network device).
  4. Use the computer to navigate to a website, or use the third-party router's diagnostics to confirm a connection to the internet.

Connection Monitoring

Dashboard

Please allow some time after installation for the Starlink app to collect data.

Starlink Statistics: If you are connected to the Starlink WiFi, from the Starlink app in the “Statistics” section, or by typing dishy.starlink.com into any web browser, you can check statistics like speed, uptime, latency, outages, and alerts. This information is also available at starlink.com/account/dashboard

  1. Downlink Throughput: Download speed in Mbps
  2. Uplink Throughput: Upload speed in Mbps
  3. Latency: Round trip time to the Starlink POP
  4. Ping Drop Rate: Percentage of "pings" sent that did not get a response from the POP. You should not experience any effects while ping loss is less than 3%
  5. Signal Quality: Signal Quality is an indication of Signal to Noise Ratio (SNR) which we represent as a percentage from 0% - 100%.
  6. Obstruction: Check to see where you may have obstructions causing intermittent service. Any obstruction level is bad for performance. If you see obstruction percentage greater than 0.2%, your install location or current surroundings is having a negative effect on performance. Anything more than 0.27% obstruction will cause enough outages for the end user to notice. In this case, please consider adjusting your install location or raising up your Starlinks to improve your performance. A Starlink should have a clear view above 20 degrees elevation , in ALL directions 360 degrees around the azimuth.
  7. WiFi Range (app only): View the signal strength of each connected device from the Network screen, use the Range tool to test WiFi signal throughout your home, and run a speed test.

The dashboard will provide:

  1. Status:
    1. Green: Your Starlink is online and transmitting
    2. Yellow: Your Starlink is online and has an alert
    3. Red: Your Starlink is offline
    4. Grey: We don't have any record of telemetry for the Starlink
  2. Any alerts related to your hardware or service.
  3. A button that allows you to remotely reboot the dish
  4. The ability to change IP policy from "Default" (CGNAT) to "Public IP"
  5. If you are using the Starlink router, you can also configure the WiFi network.

Obstructions

The dish will register any blockages that obstruct its own view of the sky, and it will generate a map that can be viewed in the app. It can take up to 12 hours to generate a complete obstruction map. This is different from the map you made in the earlier step, as this is based on where in the sky the Starlink has been able to successfully connect to a satellite.

  1. On the main menu of the app, click on the "OBSTRUCTIONS" item.
  2. On the subsequent screen, see any obstructions in the dish's view of the sky.
  3. If the view is highly obstructed, we recommend mounting the dish in a location with a clearer view of the sky.

Connecting to a Third Party Router

To connect Starlink to an existing Wifi network in your home, business, or vehicle, you need to connect to it via Ethernet.

Use the included Starlink Ethernet cable to connect from the Power Supply to the WAN port of your router.

Router Configuration

DHCP : Configure the WAN port on the router to use DHCP to automatically get an IP address

Health Checks: Relax heath checks (i.e. pings, etc.) to deal with occasional connection drops from Starlink. For example, checking every 10 seconds & getting 5 fails in a row would be a good threshold to start with.

Starlink status

The status of the Starlink antenna can be checked via the App or through your Starlink Dashboard

To access the status of the Starlink antenna from within the local network, you must configure a static route to send all traffic for 192.168.100.1 to the WAN port to which the Starlink is connected. Then you can use a web browser to view the Starlink dashboard at http://192.168.100.1


Installing Multiple Starlinks

To set up a multi-antenna connection with Starlink, please follow the instructions in this section.

Starlinks in Close Proximity

Before installing multiple Starlink antennas at a location, please review the following considerations:

  1. Minimum separation distance: The minimum separation distance from the mount center to mount center should be 0.9 meters.
  2. Minimize Obstructions: Each Starlink should have a clear view of the sky 20° elevation above the horizon, 360° around the azimuth. You may need to raise the antennas on a pole/pedestal to get a clear view of the sky & good service. If you have obstructions > 20° elevation in any direction, the performance will be negatively affected.

Networking Multiple Antennas

Using the included Wifi

The included Wifi Router can be set up separately with each individual dish using the the same network name (SSID) and password. They will work as separate, independent systems.

The Starlink Mesh feature will not be available. This means that each router/antenna pair will be isolated, and data will not be shared among routers on the internal network. If one antenna loses connection to the network, then the associated Wifi will no longer provide internet.

Your phone or other device will connect to the nearest Wifi Router. This shouldn't cause problems in general, though you may notice that your device sticks to whichever it is connected to even if you move closer to the other router.

Using a third-party router

You can use a third-party router appliance to perform advanced networking to interconnect multiple Starlink antennas at a single site. This type of equipment can provide features such as load balancing, failover, link aggregation, IPSEC tunneling, etc. Manufacturers include Peplink, Cisco, Fortigate, Versa, Silverpeak, Aruba, etc.

Network Setup:  If you are using SDWAN, please consider the following to optimize performance.

  1. Load Balancing: Set as even a load balance as possible across all terminals. This should be on a throughput basis (not sessions, or some other metric). The optimum way load balance across multiple Starlinks is to have the router send traffic to the least utilized interface based onuplink throughput.
  2. Health Checks: Configure heath checks (i.e. pings, etc.) to deal with occasional short-duration outages from Starlink. For example, checking every 10 seconds & getting 5 fails in a row would be a good threshold for flagging the connection as "down". 
  3. Throughput: If there are any obstructions blocking the antenna's view of the sky, then you can expect intermittent interruptions in connectivity. This can result in overall lower throughput for that antenna. Please take this into account when traffic shaping.

Starlink Status

The status of each Starlink antenna can be checked via the App or through your Starlink Dashboard.


Maintenance

Starlink hardware requires little maintenance if installed correctly. However, there are some things to consider to maintain a good experience over time.

  1. Make sure your install remains obstruction-free. When adding additional hardware, be sure not to block the Starlink view of the sky. Use the Starlink mobile app "obstruction" feature to show any obstructions in the field of view. obstruction percentage chart on the dashboard is also helpful for checking obstruction levels.
  2. Periodically check that the antenna surface is not accumulating salt or dust residue. If there is salt or dust buildup, clean off the off the antenna surface to remove any residue.
  3. Starlink dishes have a snow melting feature to prevent accumulation on the dish. We do not have specific performance degradation per millimeter of snow accumulation, however the terminal should be able to melt any snow that accumulates over a given time period (except for extreme blizzard conditions). If the snow accumulation is greater than the rate of heating, you may experience some temporary degradation.

Troubleshooting

  1. Check the local weather at the antenna. Heavy rain can affect the signal between the Starlink dish and the satellite network.
  2. Check your account dashboard for an overview of service status. Any alerts related to your service or account will be displayed.
  3. Check the power light on the power supply.
  4. Visually inspect your installation to make sure the surface of the dish is free of dirt, debris, and obstructions.
  5. Check your cable connections from the dish to the power supply, and from the power supply to the network equipment.
  6. Verify any connected network equipment is powered on and operational.
  7. If using a third-party router, try connecting a laptop directly to the Starlink to verify connectivity.
  8. Create a support ticket via the app (or reach out to your managed service provider).
