Antenna Auto up/down Dongle

This dongle will allow you to control a power antenna so that when you feed power into the dongle it will raise the antenna, and when you take power away it will lower the antenna.  Very commonly used on the Diamond K9000 Motor.

It will work for power antennas that use stop switches and polarity reverse to change direction.  Also used on other small motors and devices where you need to reverse polarity by sending a +12v signal.
