10 Mounting recommendations
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. The nearest ground plane
should be at least 3mm away from any point on the antenna.
