It can be counterintuitive because the user terminal is shaped like the kind of satellite dish we’re mentally prepared to understand, the kind we’ve had for the last 50 years, but it’s fundamentally different. The “clear view of the sky to the east” is the source of your problems. Starlink satellites move quickly across a the sky, and the dish needs a comparatively massive 100+ degree view angle to ensure continuous contact. If you look around online you can see comical configurations with Starlink mounted on enormous poles to get them above the tree line. This issue is the #1 cause of problems we see with new installs.
