How to Run Starlink Cable Into Your House (2026 Guide)

The most common way to run a Starlink cable into your house is to drill a single 3/4-inch hole through an exterior wall near your router, feed the cable through with a $32 official Starlink Cable Routing Kit, then seal the hole with the included grommet and silicone sealant. The whole job takes about 30–60 minutes with a drill, and no professional installer is required for most standard wood-frame homes.

What You Need Before You Start

• Starlink dish already mounted (roof, pole, or wall)
• A drill
• 3/4″ spade bit (included in Starlink’s kit) or 20–25mm bit for masonry
• Stud finder (optional, but recommended)
• Silicone sealant
• Grommet or cable gland
• Starlink Cable Routing Kit ($32, official) or off-the-shelf grommets/drill bits if you’d rather DIY it

Note: on Gen 3 dishes, the cable is permanently attached to the dish (about 15 meters/50 feet) and can’t be detached, so plan your entry hole location based on the distance from the dish to your router not the other way around. If 50 feet of cable isn’t enough, Starlink offers a 150-foot cable, or you can use an aftermarket extension on the included cable.

3 Ways to Run Starlink Cable Into a House

Method 1 — Drilling Through an Exterior Wall (Most Common)

Best for permanent setups. Clean, weatherproof, and keeps cable exposure to a minimum. This is what most homeowners do and what the official routing kit is designed for.

Method 2 — Using an Existing Entry Point

If you already have a cable/coax entry point from a previous satellite dish or cable TV install, you can often reuse that hole instead of drilling a new one. Just confirm the opening is at least 3/4″ wide to fit the Starlink connector.

Method 3 — Routing Through a Window or Door (No-Drill)

Good for renters or temporary setups. Use a flat window/door pass-through cable protector so the seal isn’t fully airtight, but it avoids permanent wall damage. This is the best option if you can’t modify the exterior of the building.

Step-by-Step: Drilling With the Starlink Cable Routing Kit

1. Pick your entry point. Choose a spot on the exterior wall close to the dish’s cable path and near where your router will sit inside. Less cable run = fewer places for problems.
2. Check for obstructions. Use a stud finder to avoid wiring, plumbing, or framing members.
3. Drill the pilot hole, then widen it using a 3/4″ bit to accommodate the connectors on the cable the Starlink cable has the same connector on both ends, so orientation doesn’t matter.
4. Insert the grommet into the hole to protect the cable from the rough edges of the wall material.
5. Feed the cable through from outside to inside, leaving a small drip loop on the exterior side so water runs away from the hole rather than into it.
6. Seal the exterior side with silicone sealant around the grommet.
7. Connect the cable to the router — the Starlink cable plugs into the left port on the back of the router, while the power supply’s barrel connector plugs into the right port.

If your exterior wall is brick, stucco, or concrete, don’t use the standard kit — Starlink’s standard Cable Routing Kit is designed for wood-frame walls, and the company sells a separate Masonry Routing Kit for concrete or masonry exteriors.

How Do You Weatherproof the Cable Entry Point?

Drill at a slight downward angle (roughly 3–5 degrees) from the outside toward the inside so water naturally drains outward instead of pooling at the hole. Seal the exterior side with silicone caulk around the grommet, and keep the entry point elevated ideally at least a foot off the ground to avoid flooding or splash-back during heavy rain.

Where Should You Route the Cable Once It’s Inside?

Run the cable along baseboards, door frames, or up into an attic/crawlspace if you want it hidden. Avoid running it parallel to electrical wiring, since that can cause interference. Use cable clips to secure it along walls rather than leaving it loose — loose cable is a trip hazard and more likely to get damaged. Keep bends gradual; sharply kinking the cable can damage the internal wiring and degrade signal.

Common Mistakes to Avoid

• Drilling too small a hole. The connector housing needs at least a 3/4″ opening you can’t just push the cable through a tiny hole and attach the connector afterward.
• Skipping the sealant. An unsealed hole invites water damage and pest entry.
• Ignoring bend radius. Sharp kinks in the cable can degrade signal quality or cause physical damage over time.
• Routing next to electrical lines. This can introduce interference into your connection.
• Not planning for cable length. Measure the dish-to-router distance before drilling moving the hole later means patching and redrilling.

Missing Angles Most Guides Skip

• Renters: Use a no-drill window/door pass-through kit instead of modifying the wall.
• Freelancers/small businesses relying on uptime: Consider running a second cable line as backup, since re-drilling later means downtime.
• Cold climates: Silicone sealant alone may crack in freeze-thaw cycles use an exterior-rated weatherproof gasket in addition to sealant.
• Detached structures (sheds, home offices, RVs): You may need direct burial-rated conduit rather than a simple wall grommet if the cable run crosses open ground.

FAQs

Do I need to hire a professional to run Starlink cable into my house?
No. Most people can do it themselves in under an hour using the official Cable Routing Kit, a drill, and basic hand tools. Hiring a professional only makes sense for masonry walls, complex attic routing, or if you’re not comfortable drilling exterior walls.

What size hole do I need to drill for Starlink cable?
A 3/4-inch hole is standard, since that’s the width needed to fit the cable’s connector housing through the wall.

Can I run Starlink cable without drilling a hole?
Yes. You can route it through a window or door using a flat pass-through cable protector, which is a common option for renters who can’t modify the exterior wall.

How much does the Starlink Cable Routing Kit cost?
The official kit costs about $32 in the US and includes a spade bit, pilot bit, routing tool, sealant, grommets, and wall clips.

Can I use the standard routing kit on a brick or concrete wall?
No, the standard kit is built for wood-frame walls. For masonry, brick, or concrete exteriors, use Starlink’s separate Masonry Routing Kit.

How long is the Starlink cable, and can it be extended?
Standard cables run about 50 feet on newer dishes and are permanently attached (not detachable on Gen 3). Starlink also sells a 150-foot cable option, or you can add an aftermarket extension.

Does the cable entry point need to be waterproofed?
Yes. Seal the exterior side with silicone sealant and angle the drilled hole slightly downward so water drains away from the hole rather than pooling at it.
