HAR antennas from MH Corbin are designed to operate reliably under adverse conditions. The original design for the antenna was for ocean-going vessels that are subjected to salt-water and high winds. The design was further customized for MH Corbin to optimize performance of HAR systems. 

Under FCC Rules & Regulations §90.242, the antenna is limited to a maximum height of 15 meters (49.2 ft). The antenna is connected to the mounting pole using a copper bracket and high strength insulated antenna mounts.
