The goals for the rotor project are - rugged robust construction, low cost, relatively easy to construct, fast, no gear train, no brake, strong enough to handle a pair of small beam antennas such as the Elk 2M/440L5 and 440L8 (Arrow antennas would probably work but I do not have any), run off DC, small, light, at least 450 degree rotation, easy to control the heading, and easy to set up and take down for portable or indoor operation. Things that are not included - the ability to handle large antenna arrays and weatherproofing. In the video the antenna turns through 450 degrees in 19 seconds. You can check the accuracy by looking at the alignment of the front element of the 70cm antenna with the left side of the blinds at the start. After rotating 450 degrees left and then 450 degrees right it is right back where it started. It is very cool.
