RM-Series Retractable Mast Headframe, 3-Sector

This is a three-sector headframe designed specifically for the APAC RM Winch-Up Mast series' bolt pattern, and bolt pattern of the series' Electric Rotator. It has holes drilled for two bolt patterns, ensuring compatibility with and without the rotator being used. The headframe mounts to the rotator with the supplied 6x M8 bolts, or to the RM mast with 6x M10 bolts. A central tube provides a fourth mounting upright.

Each vertical mount is constructed from 50 mm diameter aluminium and fully welded to a 50 mm centre column via two 40 mm diameter braces to provide a high degree of rigidity and minimal deflection/torquing. The centre column is secured to the 175 mm round base plate via four gussets. Each mount is offset 350 mm from the centre tube as standard, but customisable to your requirements.

Three-sector headframes are popular in Private LTE/5G and wireless network configurations which use 65° sectoral transmitters to enhance capacity and range. These headframes are suitable for mounting a very broad range of equipment, from CCTV cameras, to weather stations, to industrial sensors, and more.
