    Anyone have any recommendations for an EMC antenna
    for preliminary EMC testing?

    Simplicity is the keynote.

    Begin with a simple 3 to 10 feet whip.

    Then advance to a 2 or 3 feet diameter tuned loop for directional

    A multi-turn loop for VLF or a single-turn loop for HF and and VHF.

    But to discover the presence of weak interference there's nothing
    better than a 50 to 150 foot Inverted-L with a very modest ground

    It greatly depends on the frequency of interest. Antenna sensitivity
    for initial ball-park estimation of field strength can be calculated
    from antenna dimensions with sufficient degrees of accuracy.

    Receiver quality matters much more than the antennas used. Use
    calibrated spectrum analysers for important critical work.
