Using Simple AZ-only TV rotators: This topic is coverd in the remainder of this page.
For almost all of the Low Earth Orbiting (LEO) amateur satellites a modest beam antenna fixed at 15 degrees elevation is more than adequate to bring in signals from the digital packet and voice FM downlinks to your dual band FM radio. A simple TV rotator and modest beam is all that is required. This is a bargain compared to the typical AZ/EL OSCAR class satellite tracking station. And it also serves perfectly well for terrestrial VHF/UHF work as well.
In general there have been reports of some people getting ‘results’ with not particularly directional antennas being used with an Az rotator at around 30 degrees (or sometimes lower). I have a vague memory that it was with either an eggbeater or dual moxon antenna rather than a yagi though (i.e. not overly directional)
An egg beater does not need to be rotated. And, yes, a Moxon could be rotated.
The idea would be to adapt the control protocol to just turn the array as the pass comes overhead. Since TV rotors can’t go around 360 degrees, there may be some challenges for some passes that would have to go through the dead spot.
The rotator interface typically knows the limitations of the rotator it is configured for (such as with the K3NG arduino code) and if the rotator hits the overlap point it will reverse to go around and meet up with it on the other side.
The Yaesu G-5500 has hardware end stops at 0 degrees and 90 degrees (after an overlap)… so now that I think about this more I might want to change the interface settings a bit so that meridian flip happens at 0 and 450 rather than 0 and 360… hmmm…
