Starlink Circular Actuated Dish, Gen 1

StarlinkStarlink: Starlink, initiated by US company SpaceX in January 2015, is a satellite network project aimed at providing satellite internet connectivity. The project's primary objective is to deliver broadband services globally, particularly to underserviced areas of the planet. Starlink's constellation…'s Generation 1 User Terminal, known as the Circular Dish, or "Round Dishy" is a satellite terminal provided by Starlink as the main user equipment between April 2021 and early 2022. Within G1 "Round Dishy" there are two revisions, Rev1 and Rev2 which can be differentiated between visually by the Rev1 having a black mounting tube and Rev2 having a grey mounting tube. Depending on when the UT was manufactured it may have a sub-version of rev2_proto2, rev2_proto3, or rev2_proto4.

The antenna unit UTA-211 connects to its corresponding router UTR-201. Specification here refers to the UTA-211 only.

The Starlink G1 User Terminal is a satellite transceiver which uses a digital beamformer, 16 front-end modules, and 1280-element phased array antenna to track and maintain connectivity with LEO satellites as they move overhead. G2 uses motors to adjust azimuth and elevation to position the phased array to an optimal alignment.

Starlink UTs communicate using the Ku-Band, receiving a 240 MHz channel between 10.7 and 12.7 GHz, and transmiting a 60 MHz channel back to the satellite between 14.0 and 14.5 GHz. The G2 UT was replaced by "Rectangular Dishy" late 2021 which provided similar performance despite the slightly reduced antenna gain.
