RN -41 -DS

Figure 5. Minimizing Radio Interference

 

Because the RN-41-N does not contain an antenna, it does not carry regulatory approvals.

If designers use Roving Networks recommended design, they can file for a permissible antenna change and use Roving

Networks’ regulatory approvals. Roving Networks recommends the Yageo chip antenna for the RN-41-N module. For

detailed information on this antenna, refer to the Yageo chip antenna data sheet on the Support page of the Roving

If designers choose to use another antenna, they must go through the regulatory approval process.
