GC76 Heavy Duty Roof Mast, 76 mm Pole
Locally Manufactured (+1 Week)

GC76 galvanised steel roof poles are a serious, low deflection mounting platform that ensures your RF system resists even the most intense of weather conditions.

Constructed from 76.1 mm C350 grade galvanised steel pipe, this mast is built for mounting equipment with large sail areas and head loads.

This roof mast can be supplied with optional climbing pegs to aid reach to the top of the pole.

High frequency microwave transmission requires extremely strict tolerances with respect to deflection and rotation, accordingly standard 30 and 50 mm typically are not suitable particularly for links above 6 GHz. 76 mm roof masts are quickly becoming an industry standard minimum, used by just about all major microwave integrators across the globe.

This roof mast ships from our partner in the Sunshine Coast, Queensland.

Recommended Use

R-Spectrum use GC76 for mounting licensed microwave platforms, with the exception of > 60 GHz mmWave. Above 60 GHz antenna diameters are generally not less than 300 mm (1 ft) resulting in a low wind load.
