Starlink, SpaceX’s satellite internet service, uses a phased-array antenna to connect with its constellation of low Earth orbit (LEO) satellites. Here are some key details about the Starlink standard antenna:

Appearance & Design:

  • The Starlink antenna, often referred to colloquially as “Dishy McFlatface” by the Starlink team, has a flat, circular shape.
  • The design is simple and doesn’t require manual alignment to the sky, thanks to its phased-array technology. The user just has to place it with a clear view of the sky, and the antenna will handle the rest.

Phased Array Technology:

  • The Starlink dish uses phased array technology, which allows it to electronically steer the direction of the antenna’s beam and connect with multiple satellites in the sky without physically moving.
  • This is a stark contrast to traditional satellite dishes that need to be pointed at a specific location in the sky.

Self-Heating:

  • The antenna has a self-heating capability, which helps it melt snow that might accumulate on its surface and potentially disrupt the signal.

Mounting Options:

  • The initial Starlink kits included a tripod stand for easy installation on the ground or other flat surfaces.
  • SpaceX also started offering roof mounts and other mounting options to give users more flexibility in their installation.

Performance:

  • With the antenna and the accompanying Starlink service, users have reported internet speeds that range from 50 Mbps to 150 Mbps, with low latency ranging from 20 ms to 40 ms. However, performance can vary based on location and the density of the Starlink satellite network in that area.

Future Iterations:

  • SpaceX continuously innovates, and newer versions of the Starlink antenna might be developed as the technology and service mature.

When installing the Starlink antenna, it’s essential to ensure it has a clear view of the sky. Buildings, trees, and other obstructions can disrupt the signal. The Starlink app provides guidance to users during the installation process to find the best placement for the antenna.
