ABSTRACT:
An improved modular antenna pole comprised of a series of aligned cylindrical sections of progressively smaller diameters. Each of the sections includes a top and bottom transverse surface and a circular flange attached to the top and bottom transverse surfaces, respectively, to permit adjacent sections to be bolted together using conventional attachment bolts through a series of complementally spaced mating bores through the flanges. Each of the bolts is held in place by a retention clip which allows the bolts to be pre-installed. A stop tab located inside the sections prevents the bolts from rotating during tightening, and eliminates the use of a conventional jam nut. This improved design also allows the bottom flange of a higher section to rest directly on the top flange of a lower section, resulting in easier assembly and a straighter and more stable pole. Finally, the internal stop members eliminate the need for access holes in each section, and thus the present modular antenna pole is easier and safer to assemble and less susceptible to rust and corrosion, which means faster, safer installation along with less maintenance and longer life.
