Headframes

Image: 

Headframes, often called top mounts, are a type of tower extension or attachment that bolts on to the top of the tower to provide a mounting platform for large systems. These can be particularly useful for guyed towers, where guy wires may prevent attachment or interrupt the operation of the equipment.

Within our range of towers we generally provide the following headframes, all with matching bolt patterns:

-- Single Mount --
Called a Spigot. It's effectively a section of pipe attached to a plate strengthened with gussets, with a bolt pattern to match the tower series

-- Twin Mount --
Also known as a dual or butterfly mount. These are ideal for mounting sector or separating omnidirectional antennas in telecommunications applications.

-- Three-Sector Headframe --
Sometimes called a triangular head. Very common in telecommunications, which use three sectors each covering a 120 degree area.

-- Four-Sector Headframe --
Sometimes called a square head. Popular amongst TDD wireless applications such as multipoint networks which operate ABAB frequency reuse.

AL340 Aluminium Tower Headframe, Three Sector

$0

Complementing APAC's AL340 Aluminium Roof and Ground Towers, this three-sector mast head/headframe has been built to mount a range of telecommunications and CCTV equipment, but most specifically 65° sector antennas used in Private LTE radio access and in 5 GHz point to multipoint configurations.

Each vertical mount is constructed from 50 mm diameter aluminium and secured to a 70 mm centre column via two 40 mm diameter tubes to provide a high degree of rigidity and minimal deflection/torquing. Additional strengthening can be added to match your intended application.

RH360 Dual-Axis Mechanised Rotator Head, 360°, Twin Arm (Currently Unavailable)

$0

Meeting the demand for a remote controllable headframe, APAC's RH360 Twin-Axis Rotator Head allows the adjustment of lighting, antenna, and camera systems without lowering the tower or mast.

The RH360 system uses an electronic remote control to adjust the azimuthal rotation of the head, and then independent elevation adjustment of the two arms. Multiple systems can be integrated onto the one mast or tower, allowing implementation of East-West microwave backhaul or radio relay / repeater systems.
