I am planning to by the Selfsat H21D and Selfsat HH90 motor. Question I want to ask here is, whether the HH90 motor on H21D has any use. Here is my reasoning that it has no use:
The dish is small, so an accurate setup is mandatory. This means skew and elevation must be as accurate as possible. But when one looks at satellites (0°E to 72°E ) for Europe, then the corresponding dish elevation ranges from 5° to 31°, and skew from -36° tot 3°. Now, the motor only lets me adjust the azimuth, but not the elevation and skew, which means that if I watch something on Hotbird (13°E), and want to switch to Eutelsat W5 (70.5°E), I would need to adjust the elevation and skew some 30°, and azimuth some 60°. Motor will, of course, handle the azimuth, but what will adjust the elevation and skew? Because of the size of the antenna, and especially the flatness, I tent to conclude that the motor is somewhat useless for this “dish”. Or am I wrong, and is the motor designed in such a way that it automatically can change the skew and elevation when it turns?
Am I right, or wrong? Hope someone can clarify it to me.
Kind regards,
Davor
