Status: Working
Latest Release: [ ]

Introduction


Idea.png
Warning: Mounting a complete station this close to the antenna (in particular without use of shielding or shielded network cables) can result in the stations performance being significantly limited by its own noise. It is advisable to mount the LNA at the antenna, and the rest of the station as far away as is practicable.


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.
