A permanent RV roof mount gives a Starlink Mini a stable, always-ready position — no setup each time you park. The trade-off is a roof penetration that must be sealed correctly. This guide is written for the Mini, which uses its own dedicated foot and closed mount ecosystem.
1. Choose the Bracket
- Permanent drill mount: a fixed foot bracket bolted through the roof, with a sealed base plate.
- Multi-scenario roof mount: supports roof / wall / pole with multi-angle adjustment if you also use it off the RV.
- Reserve the magnetic mount for temporary use — a permanent install should be bolted, not stuck.
2. Roof Prep
- Locate a flat roof section with a clear sky view (no AC units, vents or light bars directly above).
- Mark the bolt pattern; avoid roof ribs and existing wiring runs.
- Clean with isopropyl alcohol and let dry fully.
3. Drill, Seal & Bolt
- Drill the penetration holes; deburr.
- Apply marine-grade polyurethane caulk (e.g., a UV-stable bedding sealant) to the base plate and under each bolt washer.
- Bolt down with stainless hardware; torque evenly so the base sits flat.
- Smooth a final caulk fillet around the base and let cure per the product data sheet.
4. Cable Entry
- Run the 2-in-1 combined cable through a dedicated roof gland or Ethernet bulkhead — one penetration only.
- Seal the gland with the same marine caulk.
- Route the cable inside to the cabin, avoiding sharp roof edges that chafe the jacket.
5. Power From the House Battery
Connect the Mini to a 12V→30V step-up converter fed from the RV’s 12 V house bank, or use the DC→Anderson cable for a LiFePO4 system. For shore power, the 144W 48V adapter (Mini-rated) is the clean option.
6. Test
Park in clear sky, boot the dish, confirm “connected” in the Starlink app, then re-check every seal after the first rain and after any high-wind leg.
FAQ
Q: Will a permanent mount survive a car wash? Yes — bolted mounts are fine; remove magnetic / suction units first.
Q: Do I need the magnetic mount instead? Only if you want tool-free removal; permanent installs should be bolted and sealed.
Q: Can the Mini share the house battery all day? Yes via a step-up converter; size the bank for continuous draw.
