As the loop is rather small, the wind load would also be very small, so a light duty TV rotator would probably work just fine. This would be true if the loop were to be mounted on or near ground level (where I have seen many). If you were to put it up higher, you'd probably need a higher duty rotator just because it's exposed more to the elements.
Just by way of observation, there are some comments on various Facebook pages that folks are also experimenting with using a battery type power supply to reduce the possibility of junk from the AC. Other experiments are ongoing. I rarely see such experiments being reported using the Wellbrooks or Pixel loops.
The positive reviews continue - bottom line, if you're thinking about an active loop, think of this before either a Wellbrook or Pixel. You will save cash, and it seems to work really well..;.Mike
