Starlink Cable Routing Through Walls¶
Guide to routing Starlink cables through UK house walls for a clean weatherproof installation. Covers wall drilling, cable glands, interior routing, and maintaining the Starlink cable warranty.
Planning Your Cable Route¶
The Starlink Gen 3 dish has a fixed 15-metre integrated cable that cannot be detached. Cable routing must accommodate the entire cable length from dish to router. Plan the route before drilling -- measure the distance from the dish location to the router position inside the house. The cable enters the house through a single wall penetration. Choose the entry point carefully: on the same wall as the dish if wall-mounted, or at the nearest convenient wall for roof-mounted dishes. The entry point should be at least 300mm above ground level to avoid flooding and puddles. Avoid routing the cable near electrical cables or sources of interference. The Starlink cable is UV-resistant and rated for exterior use but should not be left coiled on the ground. The minimum bend radius is 75mm -- do not kink or sharply bend the cable. For roof installations route the cable under roof tiles or through the fascia board before entering the wall. Use exterior cable clips (galvanised steel cable clips £5 from Screwfix) to secure the cable along walls.
Drilling Through Walls and Sealing¶
Step 1: Choose the entry point location. Inside the house the cable should emerge near the router location. Step 2: Drill a 20mm or 25mm hole through the wall using an SDS drill with a long masonry bit (300mm+ for cavity walls). Drill at a slight downward angle (3-5 degrees) from outside to inside so water runs outward. Step 3: Insert a cable entry gland or weatherproof wall feed-through. A cable gland (IP68 rated) provides weatherproof sealing. Step 4: Feed the Starlink cable through the gland from outside to inside. Apply silicone sealant around the gland on the exterior side. Step 5: Inside the house fit the cable through a brush plate or decorative cable entry cover. Step 6: Secure the cable to the exterior wall with cable clips every 300mm. Step 7: Create a drip loop (cable dips downward before entering the wall) so water drips off rather than running into the hole. Step 8: Connect the cable to the Starlink router inside. Do not coil excess cable tightly -- use loose figure-8 loops. For cavity walls use a cavity wall sleeve or duct to prevent damp bridging. Prices: cable gland IP68 £8, cable entry wall plate £12, exterior cable clips £5 per pack, SDS long masonry bit £15-£25.

FAQ¶
- Can I extend the Starlink cable if it is too short?
- The Starlink Gen 3 cable is fixed at 15 metres and cannot be extended or shortened. If you need a longer run consider repositioning the router or using a third-party cable extension (not officially supported).
- What size hole do I need to drill for the Starlink cable?
- A 20mm or 25mm diameter hole is sufficient for the Starlink cable connector. Use a 20mm SDS masonry bit for brick walls. For the connector use a 25mm hole to ensure it passes through easily.
- Do I need to create a drip loop for the Starlink cable?
- Yes, always create a drip loop. Route the cable so it dips downward before entering the wall gland. This prevents rainwater from running along the cable and into the wall cavity.
- Can I bury the Starlink cable underground?
- Yes but use armoured cable or run it through 20mm conduit buried at 300mm depth. Standard Starlink cable is not rated for direct burial. Use exterior-rated Cat6 extension if running beyond 15m.
- Does drilling for Starlink cable affect my UK home damp proofing?
- If you drill through a cavity wall the hole can bridge the cavity and allow damp ingress. Use a cavity wall sleeve or duct and seal both sides with silicone. Keep the hole at least 300mm above ground level. For more information see our Starlink Wall Mount Installation.
