 18-inch QARL Heavy-Duty Linear Actuator


This is our heavy-duty, 18-inch, 2-inch tube QARL Linear Actuator used to move your c band dish so that it can track multiple satellites.

It is powered by a 36V positioner (sold separately), can handle a maximum load of up to 1400 lbs and is recommended for 2.4m or smaller dish sizes.

A conventional installation on most C band dish mounts will allow you to track the satellite arc from 55-west to 139-west. NOTE: Actuator color is gray.

NOTE: This 18-inch actuator (2023 model) is a stronger version of our previous model with a thicker tube.
