    Subject: QEX article The Antenna Equivalent Radius: A Model for Non-Circular Conductors, QEX,

    I'm after a copy of the following QEX article:-

    David M. Drumheller K3WQ, The Antenna Equivalent Radius: A Model for Non-Circular Conductors, QEX, American Radio Relay League, Newington CT,
    2017 March/April

    Referenced here:-

    https://en.wikipedia.org/wiki/Antenna_equivalent_radius

    and here:-

    https://www.radioamateurs-france.fr/wp-content/uploads/RAF-antenne-145-mhz-ruban-1-et-2-F5JTM.pdf

    I'm trying to get round meshing issues on OpenEMs and HFSS by using
    equivalent square elements. A search suggests using a factor of
    roughly 0.59 for the equivalent radius.

    Tnx

    Brian

    Mine only go back to 2020, sorry, but you should be able to contact
    the ARRL directly and ask for a reprint. If you're an ARRL member
    they probably won't even charge.
