Blackhawk Collared Roof Mast
2 metre, 50mm diameter
Part Number: MAS-BH-00001
Blackhawk 2m Heavy Duty Collared Roof Mast
Introducing the Blackhawk range of roof masts. To help our valued network of Australia-wide installers, we've introduced a range of heavy duty roof masts to complement the standard types that you're using on your jobs. Blackhawk's range of masts are ultra heavy duty and built tough for the Australian environment.
50mm collared roof masts come into play when you need to install high gain or heavy antennas, where the standard 25mm roof masts won't support the load. Many wireless equipment vendors also require their radios to be attached to masts a minimum 35mm in diameter to ensure engineering wind load calculations are valid.
- Designed for applications requiring high stability
- Fully engineered for minimal az/el deflection
- Galvanised 48 mm (OD) pole, 2 m height
- Collared design with 5 mm thick foot plate
- Sliding collar with grub-screw attachment
Sub-6 GHz microwave transmission requires strict tolerances with respect to deflection and rotation, and the large dish size associated with the lower frequency operation can add significant wind load. 48 mm roof masts are essential for reliable operation of point to point / multi-point wireless transmission in any weather condition. For 6 to 80 GHz microwave transmission we recommend the 75 mm roof mast.
The collared design encorporates a sliding collar allowing stay bars to be attached to the centre mast without invalidating the engineering certification by drilling new holes to vary the stay bar pitch angle. This design is safe, fast, and heavy duty, and is available in a range of different heights. The footplate has a hinged design allowing pitch compensation for standard corrugated iron and tin roofs.
