You would not need a Rotor, since the majority of the stations you get are coming from 81-88º, so no really having to move the antenna. Now of course it will also pick up off the backside with no problem. I get the local PBS which is at 235º on the Compass off the backside of my DB8. The front is pointed around 78º at Center for the NBC & CW towers in my area, but will pick up the towers around 90-96º, that are the towers for ABC, CBS, Fox, but use the YF-5713 to get a better reception for the CBS, since I would get very low Signal how the DB8 was pointed for the range that I wanted.
I just had to tweak a little bit using the CW tower and the PBS to try and fine tune in the strongest for those two, which in turn got me the strongest for the NBC, due to the CW, NBC towers are the farthest from me for my area, but the PBS is a lower power repeater. It is a trial and error to get your antenna the best. I of course also cheated and used the Winegard SensarPro signal meter, modified in a box, and just for Antenna Input only, and a power supply, so that I could use it up in the attic while fine tuning both antennas.
When you get the antennas on the mast with the Rotor, you want the Rotor at North, and the Antennas also at North, so that when you adjust the rotor the antennas will point in the correct direction.
