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
Networks website at http://www.rovingnetworks.com/Support_Overview.
If designers choose to use another antenna, they must go through the regulatory approval process.
