The chosen antenna is selected by soldering in the 0 ohm towards this antenna, the other serial components are then Do not mount. In general, use a shunt and a series element at the output of the RF-pin towards antenna, to allow for slight impedance tuning if required. Add zero ohm towards each antenna if you want to have several options for antennas.
