Elevation nearby 90°


just a question, I would like to know how is acting your rotator when following a satellite at nearby 90° of elevation ?

thanks for your response


Then it is pointing straight upwards. The chance of having an exact 90 degrees angle is almost zero for a given position when tracking satellites, but mechanically it is no problem. There is always an azimuth position available so when the satellite passes straight above, the antenna turns 180 degrees in azimuth and continues tracking the object.

Meaning, when it is in zenith the actual pointing direction is almost constant while the azimuth rotates, but depending on what antenna you have it does change the polarization of the antenna which can affect how you receive signals.
