Mounting Recommendations
11.1
Recommended Module Locations for On-Board Antenna
For maximized performance please orient the device with the antenna as close to the outside of the
housing as possible. Best performance will occur if the underlying PCB does not have a ground plane
under the area where the antenna is located. A ground plane directly underneath the antenna region will
drastically reduce the range of the module. The absolute minimum nearest ground plane should be 3mm
away from any point on the antenna; 5 mm or greater is preferred.
