Yes, it is due to too strong signal when plane is nesrby. Reduce gain setting. If it is default -10, try 49, 45 and 40 dB gain setting.
A higher gain antenna like V-stub, or FA or Adsbx etc picks the cell mobile signal also better, and if these are strong in your location, they can overload the dongle. Generally adding a filter in such cases solves the problem.
