Starlink Obstruction Map and 3D Mounting

Use the Starlink app obstruction map and 3D-printed mounting solutions to overcome obstacles and improve signal quality. This guide covers reading obstruction maps, mounting adjustments, and custom 3D-printed brackets for UK installations.

The Starlink app includes an Obstruction Check tool that uses your phone camera to scan the sky and identify obstacles. The tool shows a circular sky map (fish-eye view) with blue areas representing clear sky and red areas indicating obstructions. The accompanying obstruction percentage indicates how much of the sky view is blocked - aim for under 1% obstruction for optimal performance. Over 5% obstruction causes noticeable dropouts every 2-15 minutes. The obstruction map updates in real-time based on the dish's actual connection data. The app shows the expected outage frequency and duration. Interpreting the map: obstructions at the northern edge of the map affect Starlink more than southern obstructions because satellites pass from north to south in the UK. Trees are the most common obstruction in UK installations - deciduous trees in winter may have 0% obstruction that rises to 5-15% in summer with full foliage. Buildings, chimneys, and neighbouring roofs also cause obstructions. The app obstruction tool should be used before permanent installation.

3D-printed brackets and adapters provide custom mounting solutions for difficult Starlink positions. Popular 3D-printed designs available on Printables and Thingiverse: Gen 3 kickstand wedge (adjustable angle 10-45 degrees for tilted roofs), Mini USB-C port cover (weatherproof the Mini USB-C connector), Cable guide clips for neat cable routing, Obstruction avoidance mount (extends the dish 200-500mm above the roofline for improved sky view), and Mini table mount for camping. Recommended printing materials: ASA (UV resistant, suitable for UK outdoor use, £25/kg) or PETG (good UV resistance, £20/kg). PLA is not suitable for outdoor UK use as it degrades in sunlight. 3D printing services in the UK: Hubs.com, 3D People, and local libraries offer printing from £10-£30 per bracket. For permanent installations consider aluminium custom brackets from a local fabricator (£50-£100). Bracket design must account for Starlink wind load: the Gen 3 dish has a surface area of 0.2m2 experiencing up to 50N wind force at 70mph. Design the bracket for 3x safety factor.
