Starlink Cable Repair (1st Gen)

Table of contents

Oh no! You have damaged your Starlink cable...lost your internet and now have to wait for a replacement from Starlink, or do you?

Disclaimer: If you can, it is always best practice to use Starlinks supplied parts and equipment. This is ideal, but in real world situations you will find that it is less than ideal if your Starlink system breaks down and you're waiting for parts. You may have other solutions that will get you back up and running without the long delay. In this article we want to cover some of the basics of Starlink connection repair, we cut open a 1st Gen system cable and replace the connections (you will find a link to a kit near the "surge arrestor" category giving you the right tools for your own connection replacements) read on and lets see how this goes.

Starlink cabling runs direct from Dishy as one piece, connected at Dishy, with one run directly to the power pack for Gen 1 and to the router for Gen 2 systems. Because Gen 2 uses proprietary connection you have limited options as to what you can do, but with the 1st Gen system you're able to cut into the Cat Cabling and install a connector to replace the damaged portion of cabling.

The 1st Gen system uses a 100ft long cable that is attached at Dishy. This cable (if damaged) means you have to get a replacement unit, which could be pricy.

If you're going to go this route you need to consider a few

things first. The kind of cable to use, Cat5E and Cat6A are both usable but we would always recommend getting the best possible as the internet is a fickle beast and you will be chasing down problems from poor equipment for a long time to come. Use the best and don't cheap out, it may only bring you grief. Check out this link to learn more on cabling The cable must be rated for outside burial use, don't use indoor cable, as it will work well at first but will deteriorate quickly in the weather (making replacement needed every few years if not yearly). Bury the cable! People will often hang cabling incorrectly, there is a lot of weight pulling down on long extended runs and this is amplified by frost build up or critters running on it. The stress stretches the cable and will cause internal breakage, Not to mention branches and snow that will cut the cable when falling. Buried in the ground you have no worries of these impediments, you only have to worry about larger weights crushing the cable in the ground which probably won't happen as we're already referring to being surrounded by trees. If you do need to cross a roadway then make sure the cable is in a conduit to protect it from getting crushed, conduit can be found at most local hardware stores. If you're really worried about cable being damaged in the ground then you could run conduit for the whole distance, this is a great idea and if something does go wrong with the cabling you can easily replace it by pulling a new run through the conduit instead of digging up the ground.

What length can you extend too? We have tested out at a 500ft total length and had nothing, 400ft nothing, 300ft and we have signal and the system seems to be working just fine. We did this using a surge protector that extended the existing 100ft Starlink cable into the surge protector and out the other port another 200ft to the power pack in the house. For more information on the surge arrestor check out this link The overall length was just over 300ft and the system has been working well, but time will be the test as the power pack(Brick) is working harder to push the POE for the dish down 300 plus feet of cable compared to the factory 100.

*A specialty tool and crystal ethernet connectors will be needed to make this repair, a kit can be found on Amazon following the link below* -

300ft is a long distance that can possibly help get you Starlink services (depending on your situatuion), but first consider other avenues like tree trimming or tower mounting, as you might be able to stay within the factory settings of the Starlink system and prevent premature wear. If this is the only option then this will work, and will work well if done properly. Make sure that the power pack has some cooling ability, prop it up and if possible have a fan pushing air on it. It's extra work for the power pack to push through the extension, creating more heat to be carried off. If you can't get a fan make sure it has space and proper airflow getting around it. VERY IMPORTANT as this could affect the life of the system. If you can get away with the provided cable length then I would advise to do this when possible. Adding cables will create areas that will need maintenance over time making troubleshooting a little bit more tricky. That being said it can be extremely useful under certain circumstances. We ran the Starlink system at 300Ft with no problem for a couple months. Using a 200 Ft Cat6E Cable through a surge protector that connects the 100ft Dishy cable making for a total of 300ft. We definitely noticed the heat emanating from the power pack was much greater. Our one challenge was the red light came on the router, but after a few resets it came back on. This is the first time it had more difficultly coming back on. Typically takes 10 mins this one took an hour before it came back online. There was little deviation in speed tests, (as we have tested in the past Starlink hardwired always performs better).

With some of our installations the houses have been pre-wired with Cat5/6 cabling, in order to utilize this cabling, and save drilling holes through walls, we simply set-up a surge arrestor and connected the Starlink system up to the house cabling via the surge arrestor. This came in really handy a few times as the homes were completely finished and would've been very difficult to get the cabling into the home without cutting out drywall. The downside to all of this is that your putting more connections inline with the system, the more connections the more spots for failure especially if the work is rushed and hacked together. Better to take your time and do it as best you can to help your internet stay online with the least amount of issues. If you do have problems then Starlink will not be able to diagnose problems with your installed equipment, that will be on you. So make sure connections are done well and kept dry and easily accessible.

Conclusion: The Starlink has worked well for a couple months now with a 300ft total extension. There was one moment where the system came up with a red light and took a few reboots to come back online. This could've been caused by the extension but it is also a common problem found in systems without any extensions. The biggest concern was the heat coming from the transformer, very hot to the touch. It runs warm when working normally but you can feel the difference in heat so make sure it has room to breath for cooling. Better yet, mount a fan for airflow across the device. I would definitely try everything possible to use only Starlinks existing equipment and only use this as a plan b scenario. There are other options for extending Starlinks capabilities, like Ubiquiti wireless links that can extend the signal for kilometers.. but those are articles for another day.

Did you ever experiment more with removing the EMI? Mine has been damaged and I have to repair the cable past


I have replaced the first generation Starlink cable with direct buriable CAT6 and can attest to the electrical attenuation in this post. While the Amazon kit is fine for a person who wants to be frustrated, or loves extremely tedious work, I would recommend TruCable CAT6 FTP direct buriable cable and their CAT6EZ shielded pass through connectors along with a CAT6EZ tool (Amazon). Why you may ask? Because CAT6 wire diameters are slightly larger than CAT5 making the wire offsets failure prone without the EZ pass through connectors (and the TruCable connectors actually fit over the larger diameter FTP cable). You will need a cheap RJ45 cable continuity tester. The great news is the EZ connectors make it easy to…
