We stock long-run replacement cables for extending the distance between your Starlink dish and router/power supply — including lengths up to 60m, built to a higher spec than most aftermarket alternatives.
Which cable do I need?
Cable type depends on your Starlink generation — they are not interchangeable:
- Starlink Gen 3: Premium Outdoor-Rated Cat6 RJ45 cable, 24 AWG, available from 0.5m up to 60m.
- Starlink Gen 2: SPX replacement cable, 24 AWG, available from 1.8m up to 92m.
- Starlink Mini: DC-DC power cable. The genuine Starlink DC-DC cable is available up to 15m. Our own SpaceTek replacement DC power cable extends further, from 0.2m up to 20m, for setups that need a longer run than the genuine option provides. Mini doesn't support the same long-run SPX/RJ45 cabling as Gen 2/Gen 3.
Always confirm your exact Starlink generation before ordering, since the connectors are different and cables aren't cross-compatible.
Why our cables outperform standard aftermarket options
Our Gen 2 and Gen 3 cables are manufactured using true 24 AWG conductors, thicker than the 26-27 AWG wire used in many generic aftermarket cables (remember: a lower AWG number means a thicker conductor). This means lower resistance and less voltage drop over long cable runs — particularly noticeable at the longer end of the length range.
Gen 3 cable: Cat6 vs Cat5e — why it matters
Our Gen 3 replacement cable uses Cat6 FTP (foil-shielded twisted pair) construction, rather than the thinner Cat5e commonly used in cheaper generic cables. The key practical difference:
- Cat6 includes a central plastic spline (cross-separator) that physically separates the internal twisted pairs. This reduces crosstalk and electromagnetic interference, giving cleaner data signal and more stable performance, especially over longer cable runs.
- Cat5e typically doesn't include this separator, making it more susceptible to interference — a bigger risk for outdoor, long-distance Starlink installs than for a short indoor network patch lead.
Our Gen 3 cable also includes an IP67-rated waterproof RJ45 plug pre-fitted for direct terminal connection, rather than requiring you to terminate your own connector.
Do longer cables affect performance?
Longer cable runs can introduce voltage drop, particularly on DC power cables. If you're running close to the maximum available length, an outdoor-rated cable with a good gauge (lower AWG number = thicker conductor) is recommended, and where possible run power separately from long data cable runs rather than relying on a single very long combined cable.
Weatherproofing or extending a long run
If your cable needs to be joined, extended, or routed through an external wall, we also stock an IP68-rated waterproof cable joiner and an IP68 bulkhead data socket designed for outdoor Starlink installations — worth using at any join point to keep the connection weatherproof and dust-proof. For Gen 3 setups, our weatherproof RJ45 cable joiner also lets you combine two cable lengths together if you need to exceed a single cable's length.
