Average Reviews:
(More customer reviews)The product is easy to install and operate, and it performs basically as advertised, but there are a few things to grumble about.
First, communication over the control cable is one-way, from the control box to the motor. That means that the controller doesn't really know where the antenna is pointing. Rather, it knows, or thinks it knows, how fast the antenna rotates and figures how long it should take to get to where you want it and then assumes that it got there. My experience is that if it is really pointed where the controller thinks it is and you command it to rotate 180 degrees in one continuous motion, it will go somewhere between 170 and 190 degrees or so, but if you use the UP and DOWN buttons to "tweak" the pointing for best reception, the allowance for acceleration is not all that great, and you can easily have the antenna pointing 20 degrees from where the controller thinks it is. Second, the errors accumulate: if it starts from an inaccurately known position, it will end up with even less accuracy.
There is a "resync" feature, which consists of commanding the motor to turn counterclockwise long enough to give confidence that it's reached the "zero-degree" stopping point. That gets things back to a known condition, but it takes about a minute every time you resync, which is a pain. It would be much handier if the display reflected an actual MEASUREMENT of the position rather than a dead-reckoning guess.
Nevertheless, the unit does its job, and I have had no problems with it. If it's a little off in pointing, you can always do a fine adjustment with the UP and DOWN buttons. Maybe I was expecting too much for the price paid.
