They are small, easy-to-install, and low-cost structures, making them an excellent option for installation in elevated locations like building rooftops. They are best suited for moderate loads, meaning fewer antennas. Their height ranges from 6 to 24 meters. They are commonly used to support the installation of fiber optics, GPS antennas, and 4G and 5G equipment.

They consist of one or several truncated cone-shaped elements with a polygonal cross-section. For design purposes, material quality, and manufacturing standards, we are governed by the following standards: ASTM A123, ASTM A153, ASTM A570, and AWS D1.1-74.
