    As you can see from their power output curves, you will get little output in the frequency range you indicate because the wavelength is so long. Are you sure you want kHz and not MHz? Sub 150kHz, most standardised emc testing is done with conducted tests, not radiated.

    Are you testing to some standard, or is this for investigatory work?

    If this is for investigatory - then I can only re-recommend that conducted measurement setups are so much easier to utilise for the frequency range you are interested in (especially as they are the end benchmark that is used for compliance). An oscilloscope plus a good understanding of parasitic levels and pathways are the other key aspect of design, especially if you can simulate the equivalent circuit, and if the oscilloscope has fft spectrum analysis.

    Ciao, Tim
