What kind of antenna options are available for the RM1xx module and how much do they cost? Will a PCB traced Antenna work? Please reference the certified antenna list in the Datasheet (HIG) for the LoRa/BLE modules.

To get the most range out of the LoRa module it is recommended that an external dipole antenna is used rather than a PCB trace antenna. However, if range is not going to be an issue and none of the approved antennas will work for you application we do offer EMC testing/certification services and could certify any PCB trace antenna you would like through our in-house certifications lab for an additional service fee. As to the cost of the antenna options and/or EMC services, we ask that you contact support or your Regional Sales Representative for that information.
