From the RF front-end, antenna 2. From the PCB itself, other (i.e. non-RF) traces Reducing the conducted harmonics as much as possible always makes sense, since antennas can have quite large gain on the harmonics too. So, the first step has to be to get good and quite clean conducted spectrum in any case.
