Introduction
No-Rotator ground station uses a static antenna usually in VHF. A Turnstile antenna that tunes at ~137MHz is used for NOAA satellites. Some Turnstile antenna design, are wide enough to receive VHF band at 144 - 146 MHz. For more vertical satellite passes, UHF Helical antennas receive satellites at 432 - 438 MHz, e.g. [1]
Same setup could be used for a ground station with rotator.
