Starlink cable length and routing: what should you check?

A 10 m gap can need more than 15 m of cable

For example, a 10 m outdoor run, a 4 m wall drop and a 3 m indoor run already total 17 m, before allowing for bends or slack. If the supplied cable is too short, check the longer cables sold for your exact kit or reconsider the dish position. Do not buy a mount on the assumption that any Ethernet extension will fit.

Know where your kit connects

Standard’s dish cable carries power and data to the router. Mini has an integrated router and its supplied 15 m cable carries DC power. Decide where the router or power supply will sit for your kit, then measure back from there. A separate Mini Ethernet connection is another cable to plan if you want to bring the network indoors by wire.

Do not splice or bury the dish cable

Starlink advises against modifying its cable or joining cables for extra length. Its cable guidance says the cable is not rated for burial or underwater use. Keep it away from sharp kinks and doors or windows that could crush it. If the route needs to go underground, have the route assessed before buying or digging.

Agree the building entry before drilling

A cable entry needs a suitable route through the wall and a weatherproof seal. Check the wall construction, the connector size and the position of hidden pipes or electrical wiring before any drilling. Measuring only the cable thickness can leave a hole the connector cannot pass through. Starlink sells cable-routing and masonry-routing kits, but the right accessory does not replace the skill to use it. If you are unsure about the wall or sealing it, agree the indoor route and have an installer make the entry.
