ATF-V500 Installation Guide

Unit ships fully assembled and ready to install.

IMPORTANT: As shipped, the actuator position is fully retracted. Do not allow the actuator rod to rotate. The rod should be set 2-turns from bottoming out while actuator is fully retracted. I encourage you to operate the unit before putting it on the roof. When testing, be sure to hold on to the rod end to keep it from spinning out of sync while the actuator is in motion. To wire the unit up for testing, refer to instructions below.


The best way to set up the tilter is by mounting your rotator to a temporary mast on the ground. I always set up every antenna I test on the ground before carrying it up the ladder to install on the roof. It is much safer and easier. I like to drive a piece of mast, conduit, or pipe into the ground using a sledge hammer and a block of wood, then clamp your rotator onto the mast. If you cannot mount it on a temporary mast, have someone hold onto the tilter while installing the antenna and testing it.


Insert the tilter into your rotator and tighten the clamps. Index the tilter to your rotator as shown above.

IMPORTANT: Create a service loop in your cables to allow rotator to rotate a full 360 degrees. Use zip ties or electrical tape to secure cables to your mast. If you use zip ties, be sure not to tighten them too tight on the coax cables or you may crush the soft insulation and decrease the performance of the cable run.


The vertical extension of the actuator can be adjusted by loosening the two pinch bolts and sliding the actuator tube up or down. By changing the vertical extension you can change the tilting range. The default location is with a 3/4" gap between the rubber seal and pinch clamp.


Mount your antenna's boom to the pivot platform and actuator mount. Install one flat washer, lock washer, and nut onto each u-bolt thread. When tightening, keep the u-bolts perpendicular to bracket. Only tighten the nuts until the lock washers have flattened, otherwise you may crush your antenna boom tube. While tightening check the plane of your antenna and reflector to keep it square to the mast.


The default spacing between the pivots is 8.50". You can vary this distance to change the range of the tilter. Decreasing the distance will increase the tilting angle, be sure your antenna has enough clearance. Increasing the distance will reduce the maximum tilt angle, but can increase the controller resolution.
Remove the black plastic cap from the bottom of actuator. Strip about 3" of outer jacket from the cable to expose the wires inside. Peel back and cut away the foil shield from the sensor wires. Strip about 1/2" of insulation from each wire. Insert the cable through the strain relief grommet. Connnect the large black and red wires to the motor power terminals. Connect the two small wires to the sensor terminals. I also wrap a zip tie around the cable to prevent it from pulling past the grommet.

WARNING: Do not connect motor wires to the sensor terminals or the sensor will be damaged when power is applied.


There is a wire diagram inside the plastic cap, use this as a quick reference.
  • RED - RED


Note: The cap must have drain holes drilled in each corner for drainage. A-Tech has already done this for you, but if you ever need to replace the actuator, be sure it has drain holes.


Controller has easy to use push-lock wire terminal connectors. Four wires are used to control actuator, two for motor power (36VDC) and two for the feedback reed sensors, the +5V terminal is not used. Connect wires as shown, colors may vary with different cables, just be sure to make the same connection at the actuator and controller.
  • RED - M1
  • BLACK - M2
  • BLUE - SEN

WARNING: Do not connect motor wires to the sensor terminals or the sensor will be damaged when power is applied.

Simple infrared remote allows you to move the tilter in fine steps using the left/right arrow buttons. Preset positions are accessed with the up/down arrow buttons. Preset positions can be programmed from the remote and saved into memory. Refer to the controller's OPERATION MANUAL for more details.
