Universal Satellite Linear Actuators

satellite dish actuator

We have been designing and manufacturing TVRO actuator since 2003. In the last decade, our actuator models including HARL, QARL, and DARL series have scaled the heights of popularity.

The actuator is a cost-effective but heavy-duty tool with high torque. Though it is ideal for elevation systems, you may need to make an effort to fit it in your home antenna systems.

The market is overflowing with different types of TVRO linear actuator models. Though they have different lengths and require different voltages depending on the manufacturer, the majority of the models are between 8 – 36″ (inches). The voltage supply is between 12 to36 V depending on the model.

The actuators have two adjustable limit switches (stoppers) inside the bottom cover of the gearbox. Thus, you can adjust the upper (90°) and the lower (0°) limit to protect the mechanical components of the elevation system from any possible damages such as broken brackets.

The mechanical components usually get damaged if the actuator pushes/ pulls them over-the-limit. Using the limit switches, however, allows the elevation system to move between 0 to 90° degrees safely. For example, if the actuator reaches the upper or lower limit, the limit switch cuts off the motor’s voltage supply. To move it again in the reverse direction, you need to reverse the Voltage polarity. For details, read the instructions in the user’s manual carefully.

Apart from the linear satellite actuator, we began manufacturing a new H-H motor for satellite dish in 2006. For more information, refer to the following FAQs.

Motorized Satellite Dish System FAQs:

Do I need a separate power line to connect to the HH Motor?
No. The motor gets its power from the receiver using the same coaxial cable running from the receiver to the LNBF on the dish. You simply need to disconnect the cable from the LNBF and connect it to the HH Motor. Next, run a short coaxial cable between the motor and the LNBF and you are all set.

How do I control the motor to move it in the East / West direction?
The receiver remote controls the motor. Every receiver compliant with the DiSEqC 1.2, 1.3 or USALS protocol has the capability to run an HH motor. Once you have mounted the motor on the satellite arc and saved the satellite locations, you can move between the satellites by changing the channels.

Can the motor also adjust the elevation variations on the dish for each satellite?
Yes it does.

Do I need to skew the LNBF on a motorized dish?
No, you don’t. Just setting the skew at 0 will allow the motor to tilt the entire dish when it moves.

What are the benefits of motorizing the dish?


Adding a motor to your system will allow you to receive satellite channels from several satellites instead of one. In short, you will get more channels without investing in several dishes and switches.

Super jack tags are available all the time! You can choose a suitable actuator for your satellite dish or solar panel from our QARL, HARL, or the HV product series.
