AL340 Series Aluminium Tower Headframe, 4-Sector

APAC's AL340 headframes are designed to attach to the top of any AL340 series lattice tower module. This four-sector headframe mounts to a standard AL340 bolt pattern with the supplied bolt kit.

Each vertical mount is constructed from 50 mm diameter aluminium and fully welded to a 70 mm centre column via two 40 mm diameter braces to provide a high degree of rigidity and minimal deflection/torquing. Each mount is offset 400 mm from the centre tube.

Four-Sector headframes earned their name from traditional wireless network deployment which used an ABAB frequency configuration, such that radios using a shared frequency were placed 180° to each other for maximum isolation. These days, this type of headframe is more commonly used for mounting a broad set of equipment for projects requiring a mixed collection of wireless radios, cameras, weather monitoring sensors, etc.

This headframe is part of the AL340 ecosystem, allowing it to be attached to any AL340 series module using the common bolt pattern.
