ABSTRACT:
An alignment gage for accurately positioning the azimuth and elevation angles of a fixed receiving dish antenna. The alignment gage is mounted to the dish and includes a gravity actuated pendulum cooperating with an arcuate scale for setting the elevational angle. A magnetic compass having a graduated scale is used to set the azimuth angle of the antenna. In one embodiment, the compass surmounts the pendulum so as to remain in a horizontal position. The gage is particularly adapted for use by unskilled persons for use in installing home dish antennas.
