NOTE

To ensure accurate alignment of CWS antenna, vertical and horizontal ground surface angles must be

known in relation to level and compensated for during antenna alignment.

Always perform vertical alignment first.

VERTICAL ALIGNMENT

Place digital level (4) vertically on CWS antenna (1). Take reading to determine which direction antenna must be

adjusted.

Loosen four screws (3) on side of CWS antenna (1) enough to allow repositioning of antenna without free travel.

Holding digital level (4) vertically on CWS antenna (1), pivot top or bottom of antenna until reading on level is at least

1 degree below vertical (88.0-89.0 degrees).

Proceed to horizontal alignment.
