Any pole, spire, structure, or combination thereof (hereinafter referred to as the "mounting device") taller than 15 feet, including supporting lines, cables, wires, braces, and masts, built for the purpose of mounting an antenna, meteorological device, or similar apparatus, as part of, or in conjunction with, a personal wireless services system. The height of a mounting device shall be measured from the ground, unless such device is mounted upon a structure the primary purpose and continued use of which was and is not as a base or support for such mounting, such as the roof of an existing building. In the latter case, when the mounting device is not to be measured from the ground, the height shall be measured from the height of the point directly below where the mounting device meets that portion of the structure the purpose of which is not as a base or support for such mounting, as determined by the Building Inspector.
