Starlink Cable Lengths and Optional Extensions

The Starlink cable provides a connection between the Starlink antenna and Wifi router, carrying power and data. Most Starlink kits come with a 50 ft cable, but longer versions are available. In most cases, you can just add an extension to the included Starlink cable.

50 ft. Starlink Standard Cable

Starlink cables and connectors have evolved over the years, so it’s important to know which version you have if you need to extend your cable. In this guide, I will cover the cable specs and features for each Starlink model, offering tips and recommendations along the way.

Starlink Cable Lengths

The length of your Starlink cable depends on which dish model you have. Starlink equipment spans three major generations, each with slightly different cables and connectors.

Starlink Gen 1 Standard Circular

Gen 1 Standard Circular: The original Gen 1 dish has a permanently attached 100 ft (30 m) Starlink cable. A shielded RJ45 connector plugs into the power supply for power and data. To extend the Gen 1 cable, you can use a waterproof Ethernet coupler to attach additional lengths of CAT6 cable.

Starlink Gen 2 Standard Actuated

Gen 2 Standard Actuated: The Gen 2 Standard Actuated kit comes with a Starlink cable that is 50 ft (15 m) long. Unlike other Starlink models, this generation uses proprietary connectors at each end, making aftermarket cable extensions impractical. Instead, you can just get a longer version of the cable, like this 150 ft Gen 2 Starlink cable from Stargear.

Starlink Gen 2 Flat High Performance

Gen 2 High Performance/Flat High Performance: Gen 2 High Performance and Flat High Performance kits have a Starlink cable length of 82 ft (25 m). 82 ft is the longest cable length available. It has proprietary Starlink connectors on each end. Although similar looking, the proprietary connectors on the Gen 2 Standard Actuated aren’t compatible with the High Performance connectors.

Starlink Gen 3 Standard Kit

Gen 3 Standard: 49.2 ft (15 m) is the Starlink cable length for the Gen 3 Standard dish. Longer versions are available directly from Starlink, as well as cheaper 3rd party companies like Stargear. The Gen 3 Standard cable uses RJ45 connectors on each end of the cable, with special moisture seals. You can easily extend the length of the Gen 3 Starlink cable by adding a waterproof coupler, combined with aftermarket CAT6 cable. Check out my easy Starlink cable extension tutorial for more.

Starlink Enterprise Antenna

Enterprise: The Starlink Enterprise kit includes a 164 ft (50 m) cable that connects the antenna to the power supply. Although the Enterprise kit uses the Gen 3 Standard antenna, the Starlink cable is different. One end has the usual RJ45 connector, but the power supply end uses a proprietary connector. In order to extend the Enterprise cable, you’ll need this adapter in addition to outdoor rated CAT6 cable.

Starlink Mini

Mini: The Starlink Mini dish is unique because it has an integrated Wifi router. Because of this, the power and data doesn’t need to be combined into one cable. The Mini comes with a 49.2 ft (15 m) DC power cable. Starlink offers an optional 98.4 ft (30 m) version. Each end has DC5521 barrel connectors, allowing the Mini to be powered by a variety of difference sources.

Cable Extensions

If you need more than 50 ft, the easiest and cheapest solution is to extend your Starlink cable rather than buying a single longer version. This involves adding an additional length of cable to the 50 ft Starlink cable included in your kit.

Since the Starlink cable will be outside, you’ll want to use a waterproof Ethernet coupler to combine the 50 ft Starlink cable with an additional length of CAT6 cable. Be sure the CAT6 Ethernet cable you buy is outdoor rated and shielded. Here is what I've used in the past.

Maximum Cable Length

In my experience with all the Standard Starlink models, it’s best to not exceed 150 ft (45 m) of total cable length between the dish and router. Beyond 150 ft you risk too much voltage drop. If the voltage drops too much from the router/power supply, the dish might not boot up properly.

If you have a situation where the Starlink antenna is further than 150 ft away, there are other ways to get it to work. One workaround is to install all the Starlink gear (dish, router, power supply) where the dish needs to be, and then run up to 300 ft of Ethernet cable back to your home to a secondary router or access point. Normal Ethernet cable (that isn’t powering the Starlink antenna) can be run at much further distances compared to a Starlink cable.

Another option is to use a wireless Ethernet bridge to connect a remote Starlink system to your home. This is similar to the previous workaround, but uses wireless technology instead of running Ethernet cable in the ground.

Routing the Starlink Cable

Starlink cables are designed to be routed through an exterior wall. They connect the Starlink antenna, usually mounted on the roof, to the Wifi router inside. Routing the cable through a wall can be accomplished with a small 3/4″ hole, just big enough to fit the connector.

Be sure to check out my Starlink Cable Routing Kit Tutorial to learn how to properly route the cable inside.

Can the Starlink cable be buried underground?

Starlink cables are not rated for direct burial, but they can be buried underground if they are run through conduit. I recommend at least 1 inch conduit. Avoid sharp bends due to the shape of the connectors.

Is it ok to just lay the Starlink cable across the roof?

You don’t have to fasten the Starlink cable down to your roof. I recommend just laying it on the roof, routing it to the wall where it will go down the side of the house. Starlink cables are rated for outdoor use, so they are UV resistant and can withstand rain and tough temperatures.

Can I use my old internet or satellite coax cable for the Starlink?

You can’t use other types of cable for Starlink. Starlink cables are CAT6 Ethernet, designed to carry quite a bit of power and data between the dish and router. Old coax cables from other satellite systems aren’t compatible. You’ll need to run the Starlink cable instead of relying on any existing wiring.

  1. I have a Gen 1 (round) dish, with the permanently installed cable. My dog chewed the cable off near the dish, right at the hard plastic cylinder in the cable. This plastic cylinder is ~5/8″ dia. and ~2″ long – there’s another one at the router end of the cable – don’t know what they are. There’s not enough wire length left at the plastic cylinder to install a connector. If I remove that cylinder and splice in a set of connectors, will the system still work? I ordered a new cable, and of course it’s a Gen 3 cable, even though the good folks at Starlink know I have Gen 1 gear ): . The Gen 3 cables appear to have the same connectors as Gen 1 … is there any way to get at the connection inside the dish? At this point I’m willing to disassemble the dish, as it’s now junk anyway.

    1. The cylinder is a ferrite choke, designed to help filter out some unwanted frequencies. You can try cutting the cable above the ferrite choke to install an RJ45 connector. A waterproof shielded Ethernet coupler can be used to connect to the Gen 3 cable you purchased, or you could just add another connector to the existing Gen 1 cable and connect both ends with a coupler.

  2. Question: What is the amount of signal loss associated with coupler-splicing two 50-ft cables together? Please advise. Thanks.

  3. Good morning you all!
    I am building a new house in Aiken, SC and wanted to install the Starlink cable before the electrical & drywall work is completed.

    So I want to buy the STARLINK antenna in six months when the house will be completed.

    What is the latest version to buy in May 2025 for equipment, cables?

    Where do I buy the STARLINK SYSTEM in my 29803 zip code?

  4. I have an existing V2 dish and router and want to upgrade to the V4 dish and V3 router setup. The V2 cable is run 150′ underground in conduit that would be a nightmare to pull and run a new cable – can I use the existing cable with the new system? The V2 has the strange proprietary plugs

    1. Can you use the existing V2 cable to run two new pull strings? Then use one for the V3/V4 run and the other to keep for future use?

    1. Not sure what you mean, could you say it another way? The AC power cable connector will be different than the cable for the dish.

  5. Hi Noah,

    I have a Gen 1 Set up and it seems like the cable is hard wired to the dish. Is this Correct?

    I’m building a new house on my property and would like to move my dish over there when the house is finished. Right now I’m roughing in all my utilities and would like to bring the cable from the roof though the walls into a room where I’ll keep the router. I contacted Starlink and they said they no longer sell the Gen 1 Cables.

    So… I’m not entirely sure what to do. Can I just buy some sort of cable, run that, then splice them together at the ends when I move my dish? If so what kind of cable do I buy? would Cat 6 work?

    If this isn’t an option, Do you have any ideas on a solution other than just buying an newer Generation of dish?

    Thanks

  6. Hello, I purchased the starlink service for my apartment. I live on the 6th floor and the building is 21 floors. The antenna does not work on the balcony of the apartment due to the obstruction, so it is necessary to install it on the roof of the building. I have a problem because the height is approximately 60 meters, the longest cable they sell does not reach the height, so how could I install the service? Could you help me with that?

    1. You would need to install the router and power supply in a separate location, closer to the roof. Then, run an Ethernet cable down to your unit, and use your own aftermarket router.

      1. I’ve seen these intermediary adapters “https://spacetek.com.au/products/starlink-spx-to-rj45-adapters-pair” would they be safe to use?

  7. I don’t know why these companies feel they MUST have custom non-repairable or replaceable connectors?

    The standard residential system cable has YUGE right-angle connectors at each end thus making it virtually impossible to phish alongside an existing cable run through a wall plate.

  8. Hey what would you recommend doing if the span is about >2000ft? that seems a bit far for cable but is it doable point to point wireless?

    1. Possibly, but I have no experience with solutions for that kind of distance. I would recommend reaching out to Ubiquiti to see if they have a point to point that can handle that kind of distance.

  9. What options are available for extending the cable between the Antenna and the ethernet extender for the vessel, considering that there is no cable extension specifically designed for Maritime use?

  10. What options are available for extending the cable between the Antenna and the ethernet extender for the vessel, considering that there is no cable extension or longer cable specifically designed for Maritime use?

  11. Hi. I have to be 200ft from my house for a good location fir my starlink. Any suggestions on how to do this? Thankyou in advance.

  12. I would like to install Starlink on my home. I already have another internet dish mounted on my roof. The cable from that dish runs along the exterior about 90′ to a telecom box mounted on the side of the house. Inside, it is spliced to a cat5e cable. The cat5e then runs from the box to my router inside the house. Is there any way to run the Starlink cable to the box and connect it directly to the existing cat5e? I’m not sure how that would work with Starlink’s PoE cable.

    1. You could do that if there is AC power available at the box, and room for the Starlink router and Ethernet Adapter. You could have the Starlink router and Ethernet Adapter installed in the box, with the Starlink router in bypass mode. The existing CAT5 cable connects to the Ethernet Adapter in the box, and then to your own router inside the house. The existing dish cable is probably coax? It won’t be usable, you will have to run the Starlink cable from the dish down to the box.

      If no AC power is available in the box, you will just have to run the Starlink cable from the dish, to wherever you want the Starlink router installed inside the house.

        1. All the prices I list on this site are for the US market. Starlink only sells directly from the site, Starlink.com. You can find them in the Shop section under your account dashboard, or at shop.starlink.com. You need to be logged in to view the shop. Prices in the Starlink shop vary by market.

  13. Hi Noah — thanks for the fantastic blog. From your entries, I see that (1) the maximum run for a Starlink cable is 150 ft., and (2) there is no extension cable available for the High Performance and Business Starlnk kit. Does that mean the dish that comes with High Performance and Business is limited to 82 ft.? Or can I purchase the 150 ft. cable and use it with this option? 82 ft. seems quite limited for certain business applications but want to make sure I understand correctly.

    1. Correct, the 150′ cable is not available for the High Performance models. The High Performance dish uses more voltage and power, so they have to keep the cable distance in mind due to voltage drop and conductor limitations.

  14. Noah – do the connectors for the High Performance flat dish work with the Yaosheng Dishy V2 cable to RJ45 adapter? Thanks.

  15. Thank you for all your help… Question re the Martime service for 250/month I see it offers 50GB a month on the open sea…… What about being at the dock on land not moving Do you get access to more data at the dock that is not part of the 50/gb a month.. thanks

    1. When on land you will get unlimited Mobile data. But it will always use up your 50gb Mobile Priority data first before switching to Mobile data on land.

      1. I ordered the cable after I subscribed. It just got here.. but its the wrong one I think. Is this this it? Anyway to reach these guys to get it corrected if it’s wrong.. looks like zero cust service

  16. Hi – We have just taken delivery of the new (or newly-priced I should say) Starlink Marine. The main cable that runs between the Power Supply and the “Dish” is 8m long. This is very short for most marine applications. Do you know if I can use the 25m long High-Performance Dish Cable (looks like the exact same dish). Thanks in advance, James.

      1. seems i have to activate my account to get this cable? But I cant install without this cable… How can I order so I can have installed and then activated.. My installer wont schedule me until I have all the material.. Suggestions? I hate to pay for activation and then wait 2-4 weeks for delivery of cable and install

        1. You have to be a customer to be able to access the shop and order cables. 3rd party sellers are selling used ones at higher prices on Amazon if you really don’t want to pay for the service yet.

  17. Any thoughts on the issues associated with splicing two Starling High Performance cables together to extend the length of the 92 foot cable?

    1. You could potentially run into issues with voltage levels. The longer the cable, the more the voltage to the dish will drop. Too much distance can cause disconnections and reboots. Personally, I wouldn’t recommend trying to extend it. There are other ways around the issue of distance, such as mounting the power supply in an outdoor enclosure next to the dish, and using CAT6 or a wireless Ethernet bridge to get the signal where you need it.

  18. Can you use the long 25m starlink cable for the Business Dish on the new flat Maritime Dish ? The latter only comes with an 8m cable which is way too short for many boats. The Business Dish & the new flat Maritime Dish appear to be one in the same.

    1. I can’t confirm 100%, but I believe this can be done, the connector is the same. I remember a comment or forum post somewhere that said someone did this successfully.

  19. Have you ever cut the cable to install an Ethernet connector? It would be much easier in an RV to have a jack that the cable is plugged into outside, with the jack being wired to the router.

  20. Hey mate, that’s a great article. I have an “old” circular dish and my cable seem to be broken. What do you mean by :
    “Because this model uses standard connectors, cable extensions are available aftermarket with the use of a coupler. Starlink does not sell cable extensions for the round dish. ”
    What kind of cable should I look for? A simple cat6 cable?

    Thanks again for your help and this useful article.

    1. Yes, it’s a CAT5E cable which is pretty standard. With the round dish, the cable is attached to the dish. What I mean for cable extensions is that you can add additional length by plugging the original cable into an Ethernet coupler, and then the extension CAT5E cable into the other end. But if your cable is damaged, it is more complex. You will have to find the damaged part, cut it off, and install a new RJ45 shielded connector. And then once that is done you can get back the length you cut off by using an Ethernet coupler and extension cable.

      Hope that makes sense, thanks for the feedback!

  21. Hi – I am upgrading a solution from residential to business class – can I reuse the already installed cable for the residential and plug it into the business class dish – this would save me a load of time? Thanks

      1. Do you know what kind of cable is required for the high performance dish? It says it requires 150 watts, but I don’t know what category of ethernet cable can carry 150 watts.

        1. It’s a thicker CAT6 style cable. It comes with the hardware, you don’t have to supply any cables. It has proprietary connectors to connect the dish to the power supply.

        1. Yes, you have to have an account to purchase the accessories from Starlink. There are scalpers on Amazon reselling the cable for double the price if you can’t get the customer to purchase the cable.

  22. Hello,

    I have the high performance dish. In the box it came with a cable that has starlinks type-c style and the other end a RJ 45. What is this cable for?

  23. I need to install my starlink cable UNDERGROUND for approximately 145 from the dish to my home–is there a cable available to accomplish this? Thanks in advance!

    1. I think 145 ft is going to be too long for a cable run. Might need to look into point to point wireless from Ubiquiti. Starlink does sell the 150 ft cable, but that leaves you with almost no wiggle room on each end to work with. And the cable is rated for burial, it will need to be in conduit.
