If you have a picture of the elliptial dish you intend to use, post it here. Most likely it will NOT work with the
SG2100 or
SM3D22 because of the pole bracker diameter on the back of the dish and the way the motor shafts fit in that bracket.
If the diameter of the pole bracket on the back of the dish is 2 1/8" I would recommend the
HH100 or
HH120.
