All,
I am working on designing a rotator that the arrow antenna can snap into. I am aiming for this platform to be portable, so that it could be packed up and taken to different events. The base of the system will be a small circular rotating platform, that will provide a full 360 degree of freedom. The 'arm' that will hold the antenna itself, will provide elevation and roll control. I have seen a couple of random videos online of people that have made rotators but I haven't seen any that have the entire antenna mounted... or a system that provides for a flexible amount of movement. I am interested in talking to anyone that has hacked at something like this, in order to discuss lessons learned. In addition, i'd like to find out which motors you chose and why. The arrow antenna with the di-plexer weighs roughly 2lbs. Right now, I am looking at two different companies that provide stepper motors, namely:
