 ====Counterweight for Antenna====
-It is necessary to balance the antenna in elevation and azimuth axis in order to not wear the gear box of rotator. In elevation axis would be done either by using back mounted antennas or by mounting the center of antenna mass in the mast.

 ==== Rotator Controller ====
-Once mechanical assembly is ready, construct the [[SatNOGS Rotator Controller]].
+The default way of controlling the rotator is to use the [[SatNOGS Rotator Controller]].This works for both stepper motor and DC motor set ups (Note: If you are uing the [https://wiki.satnogs.org/SatNOGS_Rotator_Controller#Encoders the rotary encoders] these will need to be set up).
