Answer
Why is there a blank band across my Starlink obstruction map?
A smooth, unfilled band can be the geostationary exclusion zone, also called the Clarke Belt. Starlink avoids transmitting through this part of the sky to protect geostationary satellites. It is expected behaviour, rather than evidence of a faulty dish.
What should I check?
Our suggested checks are to distinguish the continuous band from separate red obstruction patches, read the app's service alerts, and compare any interruptions with their recorded times. Do not buy a taller mount solely to fill an expected blank strip.
Other missing areas can need a different explanation, especially while a map is still building. If you are unsure, send support a screenshot alongside your hardware model and the actual symptoms.
