Okay, the current official Starlink blurb is:
Starlink satellites are scheduled to send internet
down to all users within a designated area on the ground. This designated area is referred to as a cell.
Your Starlink is assigned to a single
cell. If you move your Starlink outside of its assigned cell, a satellite will not be scheduled to serve your Starlink and you will not receive internet. This is constrained by geometry and is not arbitrary geofencing.
If you could see the connection between a Starlink satellite and your Starlink, it would look like a single
beam between the two objects. As the satellite moves, the beam also moves.
The area within which this beam moves is the “field of view”. If any object such as a tree, chimney, pole, etc. interrupts the path of the beam, even briefly, your internet service
will be interrupted.
In early service, the required clear field of view is a 100-degree cone around the center of the dish (after tilting) with a 25 degree elevation minimum. Some obstructions are worse than others. Obstructions low in the sky will cause more outages because satellites are in this area of the sky more frequently.
The best guidance we can give is to install your Starlink at the highest elevation possible where it is safe to do so, with a clear view of the sky. Users who live in areas with lots of tall trees, buildings, etc. may not be good candidates for early use of Starlink. However as more satellites are launched, the field of view constraints will decrease, enabling a wider variety of users.
Most people do not accurately assess their Starlink's field of view. To ensure the best possible service, download the Starlink app to assess field of view in your desired install location before installing.
If you stay in your cell, and your movement is less than 100 deg cone and 25 Deg elevation, the current system will serve you.
Find your cell from the address search at the starlink site.
Of course the current antenna will work until wind
combine to degrade it.
