A:Answer The 150 ft cable is the longest that is offered. Although the Starlink cable conforms to RJ45 standards, we do not recommend modifying your cable or combining it with another cable to add length as we cannot guarantee the quality of service. Additionally, the Starlink cable provides a water-resistant protective seal with a locking mechanism, and is power rated specifically to the Starlink kit, therefore we do not recommend using any 3rd party cables as it may cause water damage to your Starlink. Any damages to your Starlink Kit caused by the above may void your Starlink warranty. Use at your own risk.
Cable specifications are dependent on the hardware type. Please click here https://support.starlink.com/topic?category=6&category=53 and find your Starlink hardware type.
