JukeBlox Networked Media Modules – CX Series Datasheet 8 Connectors and Connections 8.1 WLAN UFL Antenna Connector (optional) The module includes two PCB strip antennas operated in diversity mode. Alternatively, one or two coaxial antenna connectors are provided for connecting external (to the module) antennas. The choice between using the strip antenna or using the coaxial sockets is a build option, determined by the position of surface mount capacitors on the module PCB.
