Az-el dish mounts

(Azimuth-elevation mounts) This dish mounting method is uncommon. For a C-band dish, it would require three motors: one to rotate the dish assembly, one to elevate the dish, and one to rotate the feed to match the polarization of the satellite. Equatorial mounts are much simpler and much more common. Equatorial mounts normally lack one motor (the latitude motor) and thus track only geo-stationary satellites, while az-el mounts can track the whole sky.
Oval dishes for DBS systems employ a motor-less equatorial mount, sort of.
