
Evaluate that the foundation at the mounting location is not susceptible to change due to
humidity or temperature (avoid wooden mounting platforms)
Evaluate mounting locations for human access

Safe access to the radio transmission unit

Stable location/platform to stand upon

Safety considerations for installers and maintainers of the system in all weather conditions
Evaluate mounting locations to avoid interruptions of transmission

Near roof edge to avoid people walking in front of the transmission unit


transmission unit

Mounting the antenna in the middle of the roof and close to the roof surface can cause the
antenna to experience undesirable multi-path reflections

At the side or corner of a building wall without people being able to walk in front of the
transmission unit

Weather-protected location if possible

2.3 LINK DISTANCE
Measurement of the link distance is important in estimating the link availability and calculating the
expected Receive Signal Level (RSL). When using a Global Positioning System (GPS) device this
measurement can be performed using the Latitude and Longitude coordinate readings from the
proposed locations of the antennas. When a GPS device is not available, online tools like Google Earth
are also very helpful to determine the link distance. However, GPS reading will be required in order to
comply with any required regulatory registration process.
To estimate maximum distances and availabilities for a given product and region please refer to the
AireLink™ Fade Margin/Availability charts shown in Chapter 2.5.
