APPENDIX 1: USING AN EXTERNAL ANTENNA
Note: Use of an antenna which has not been certified by FCC, IC or CE type acceptance is not
permitted. Please refer to
The ZFSM-201-1 module is available as a ZFSM-201-1C with an MMCX connector for an
external antenna.
Alternatively, a module can be modified to incorporate an
connector to the board (though for the customer to do so, will void the warranty). This simple
procedure is given on how to modify the board for the inclusion of an external antenna
connector.
Qty
The PCB Trace antenna will no longer be connected and the MMCX Jack connector will be active.
