This alt-azimuth assembly rotates in both elevation and azimuth to position the polar axis toward the (true) pole. Then it is fixed and locked down (see side bolt) for permanent use. The inverted -"U" shape bracket can be rotated to match any latitude (0-90 deg)

The (blue) base plate bolts to a cement pier dug about 30-inches into the ground. Temporarily, the (unpainted) steel plate (shown below the base plate) has a welded 24-inch spike pushed into the ground to act as a support for field use, only.
