ADAPTING THE OSX ANTENNA CONNECTOR
The OSX antenna connector used on the Oncore™ GPS board will normally need to be adapted to an
SMB or BNC connector to match connectors commonly found on GPS antennas. An adapter can easily be
made using a short piece of RG-174 coaxial cable with the desired antenna connector.
