# RFI with Rotator
Sample the RFI in the area, using a rotator.
# QUICK & DIRTY
Early pre-alpha, not working yet.
# Rotator
The rotator can be in two different positions when sent
to `0` azimuth. It can be in a position of one degree minus one,
or 359 degrees plus one. The difference is in the cable winding.
If the rotator is at `270` azimuth and is sent to `0`, it will
go clockwise (looking from above) to `359` then plus one more to `0`.
If the rotator is at `179` azimuth and is sent to `0`, it will
go counter-clockwise to `1` then minus one.
So a test using `0` could actually be two different tests, since
the `359 + 1` test, the cabling has one more wrap around the
mast.
Best to not use `0`, and use `1` and/or `359`.
