Antennas
Antenna specification are as follows:
• Type: On-board PCB antenna
• Gain: 3.96 dBi
• Type: External antenna connector

This device is intended only for host manufacturers under the following conditions:
• The transmitter module may not be co-located with any other transmitter or antenna.
• The modules shall be only used with the external antenna(s) that has been originally tested and certified
with the modules.
• The antenna must be either permanently attached or employ a 'unique' antenna coupler.
As long as the conditions above are met, further transmitter test will not be required. However, the host
manufacturer is still responsible for testing their end-product for any additional compliance requirements required
with the modules installed (for example, digital device emissions, PC peripheral requirements, etc.).
