Mast stiffness is indeed an important factor to consider, especially for certain applications such as radiolink communication and satellite dishes. Here’s what you should expect regarding mast stiffness:
- Importance of Stiffness: In most cases, a stiff mast is considered a good quality mast. Stiffness is crucial for applications like radiolink communication and satellite dishes, where the power beam needs to be narrow and focused. A stiff mast helps maintain the stability and accuracy of the beam, ensuring reliable communication over long distances.
- Effect on Communication: Picture a laser pointer aimed at a distant target, such as a tower clock, from the outskirts of a city. Keeping the laser beam steady on the target can be challenging, but mounting the laser pointer on a stable surface, like a building, helps maintain accuracy. Similarly, a stiff mast helps keep communication beams steady and focused, minimizing signal loss or interference.
- Regulatory Standards: In most countries, masts are designed to allow a maximum deviation of 1:100 of their height. For example, for a 30-meter mast, the maximum allowable deviation at the top would be 30 cm. This deviation may seem small, but it can translate to significant displacement over longer distances. Adding a separation crown with additional guy wires is a cost-effective way to improve mast stiffness and reduce deviation.
- Safety and Serviceability: Stiff masts are not only important for communication performance but also for safety and serviceability. A stiff mast provides a stable platform for maintenance and servicing activities, making technicians feel safer when working at heights.
Overall, mast stiffness is a key quality factor that directly impacts communication performance, regulatory compliance, and safety during maintenance. Investing in a stiff mast ensures reliable and efficient operation for your communication needs.
