For bands below 470 MHz, the areas which are involved lie between Lines A and B and between Lines C and D, which are described as follows:

Line A - Begins at Aberdeen, Wash., running by great circle arc to the intersection of 48 degrees N., 120 degrees W., thence along parallel 48 degrees N., to the intersection of 95 degrees W., thence by great circle arc through the southernmost point of Duluth, Minn., thence by great circle arc to 45 degrees N., 85 degrees W., thence southward along meridian 85 degrees W., to its intersection with parallel 41 degrees N., thence along parallel 41 degrees N., to its intersection with meridian 82 degrees W., thence by great circle arc through the southernmost point of Bangor, Maine, thence by great circle arc through the southern-most point of Searsport, Maine, at which point it terminates; and
