5" Antenna Mast PipeDesigned for mounting all types of outdoor antennas including satellite dishes, CB and ham radio antennas, TV antennas and more. 18 gauge construction is ideal for smaller antennas, specifically UHF High Definition TV antennas, as it is lighter and easier to handle than similar 16 gauge masts. Swaged at one end, allowing multiple sections to be added together for increased length. Made in the USA
