Example of use with ANT-400-R and CDP-RX-02
When using a plastic case connect the antenna base of the ANT-400-R with a metal ground plane for antenna impedance matching. A wider ground plane is more effective for receiver sensitivity and stability.
In order to avoid influence from noise, the coax cable must be placed far away from the CPU and PCBs.
The above picture shows the antenna connected to the radio module through CBL-SMA-05-R. When using a dedicated coaxial cable for the connection, make the cable short to avoid loss from the cable and influence from external components.
