By Tech Troubleshooter at GoneTech.net – Tested on Starlink V4 dish. General tips only; see Starlink support for issues.
Imagine you are in the middle of a mission-critical Zoom call or a competitive gaming match. A storm rolls in. Your Starlink App starts flashing red: “Starlink is Obstructed.” You look outside—there are no trees, no new buildings, just rain.
Rain fade is normal: Water absorbs Ka/Ku signals, causing ‘Obstructed’ alerts (temporary).
These user-tested tips help restore service fast—no tools needed.
Quick Diagnosis: Rain vs Real Obstruction
Real obstruction: Trees/buildings show consistently red on the app map.
Rain fade: Map flashes red only during storm, clears after 5-10 minutes.
Check now:
- Wait 5 minutes after the rain stops
- Refresh the app obstruction map
- Red gone? = Rain fade (use fixes below)
- Red stays? = Real obstruction (trim trees)
90% of “rain obstructed” reports are fade, not blocks.

Why Rain Affects Starlink (Real Science of Fade)
Heavy rain (>25mm/hr or 1″/hr) attenuates signals 20-50%, showing as ‘Obstructed’ until water clears. Not a physical block—normal for all satellites.
Quick Fixes
1. Snow Melt Hack (Works 80% of cases)
- App > Settings > Advanced > Snow Melt > Always On
- Wait 1-2min for heaters (feel warmth on radome)
- Result: Water sheets evaporate, map clears
Pro tip: Leave on during monsoon season (uses ~25W extra).
2. 15° Tilt Fix (V4 Kickstand Essential)
- Raise kickstand to max OR add 1-2° shim
- Test: Pour water on dish—should sheet off immediately
- Why 15°: Factory angle optimized for snow, not tropical rain
3. Router Reset (Clears 95% Map Glitches)
- Unplug Gen3 router only (not dish)
- Count 30 seconds exactly
- Plug in—map refreshes clean
Note: Heavy rain drops speeds 20-50%; clears after.[web:13]
Caveat: Expect 20-50% speed drop in heavy rain (>0.5″/hr); full recovery post-storm.[web:13]

The “Eave” Strategy
While Starlink needs a clear view, you can place the dish near the eave of a roof that blocks the prevailing windward rain but leaves the 110° field of view open. Reducing the volume of direct strikes on the faceplate reduces the “Obstruction” triggers.
Shielding the Cable Entry
All Starlink kits use IP67 seals. Ensure your cable has a “drip loop” (a U-shaped bend in the wire before it enters the dish) so water doesn’t travel down the cord and into the sensitive IP67 seals.
Conclusion
Keep the radome dry = better signal. Use Snow Melt + 15° tilt + eave mount + drip loop. Screenshot persistent red maps for Starlink support. Expect 20-50% speed drops in heavy rain—normal for all satellite internet.
Frequently Asked Questions
Why does Starlink show “Obstructed” when it’s just raining?
Rain fade—water droplets absorb Ka/Ku-band signals (0.5-1dB per mm rainfall), dropping the signal below the detection threshold. Not a physical block; clears in 2-10 minutes post-rain.
Does Snow Melt setting work for rain (not just snow)?
Yes—activates radome heaters (40-50°C) to evaporate water sheets even at 80°F. Users report 80% success in clearing “Obstructed” alerts during storms.
How much tilt is best for V4 dish in heavy rain areas?
15-20° steeper than factory angle using kickstand. Test: Water should sheet off immediately when poured on radome. Avoid >25° (loses satellites).
Router power cycle vs dish reboot—which for rain issues?
Router cycle only (30 seconds)—clears app cache/glitches. Dish reboot (5min downtime) only for persistent red map post-rain.

Is eave mounting safe for Starlink performance?
Yes if the 110° sky view is clear. Position 18-24″ below eave edge to block wind-driven rain. Verify with app obstruction scan first.
Can I apply Rain-X or ceramic coating to Starlink dish?
No—voids warranty and may block RF signals. Factory Teflon radome already hydrophobic; heaters handle water sheets.
