With the exponentially increasing demand for data, WISP's are under pressure to maximise site and spectrum utilisation. Often the challenge faced is reaching the largest number of clients with a limited vantage point from the fibre POP - traditionally tall 'telomasts' have been used but are unsuitable for multiple sectors and most certainly unsuitable for high gain dishes.
APAC responded to the challenge by developing an ultra lightweight, climbable, aluminium lattice tower that could be easily raised on a roof with a small team.
These roof lattice towers consist of a finely machined rotating base plate, modular 3.1 metre lattice sections, guy wires, and a range of headframes. The 3.1 m sections are easily stacked meaning roof towers can be built as small as 3.1 metres with engineering certification up to 37.2 metres (21.7 metres in Wind Region C).
The tower base comprises of a 50 tonne rated, fully machined billet aluminium universal-joint. This universal-joint design allows axis locking to permit safe and easy raising, as well as the components machined from solid structural grade aluminium providing absolute peace of mind of tower integrity.
This tower ships from APAC Infrastructure in the Sunshine Coast. Additional freight charges will apply.
Recommended Use
AL220 roof towers are an effective means of increasing transmitter height. Attaching to an ordinary tin roof these towers can be installed on just about any roof configuration. They are suitable for flat, pitched, and sloped roofs, temporary demountable buildings (dongas), shipping containers, among many more.
The AL220 roof tower system is most commonly used for Sub-6 GHz wireless, but can be strengthened with the addition of anti-twist torque arms to support microwave and mmWave dishes, or CCTV cameras.
