12VDC Reversing Polarity Controller
The 12VDC reversing polarity controller as seen here mounted in the cargo-bay of my mobile, used to control the 12VDC rotator that is used to rotate my Max-Gain systems mast/antenna array when mounted in the hitch-receiver of my mobile.
The controller is activated through the use of a two-button keyfob transmitter operating on 340MHz from anywhere in the vicinity of my mobile.
When not in use, and the fact that the rotator is not left mounted in the hitch-receiver, the power-cable that is temporarily connected to the rotator when in use, is coiled up and stored near the controller until required again.
