2m Moxon antenna by VA3OMP


VA3OMP's 2m Moxon

VA3OMP's 2m Moxon antenna


Back in August I was doing some simplex D-Star and D-RATs testing with Greg, VA3OMP on 145.67MHz. He lives in the West part of Ottawa in Kanata and I live in the South in Greely so to improve the link between us Greg constructed a 2m Moxon.  The antenna is built out of solid aluminium rod and as you can see he put some craftsmanship into building it.  Greg kindly agreed that  I could post the pictures and details here.

To determine the measurements Greg used the design program at the Moxon antenna project website. Here are the dimensions.

Greg reported the built antenna had an SWR of 1.6 :1 at the design frequency.

Here are set of pictures showing the construction.

    Thanks for sharing. Looks great! I built a “hentenna” for 2M, simple and easy to build, great performance at just 35 ft. If you are an antenna experimenter, you may wish to try one.

    What a great article on a terrific project. Thanks.

  • W6BUX, Gurbux Singh:

    Just curious as to how it compares to a vertical for gain and directivity.

  • Tike:

    Unblieevblae how well-written and informative this was.

  • Rod D Whitney WD7FGX:

    When they show the two dimensions at the top as well as the total dimension at the bottom it is an impossibility. You cannot add 14.52 and 14.52 plus the unidentified gap at the feed point and come up with a total dimension of 29.04, shown at the bottom, it defies physics. Rod

  • jack va3jfw:

    the dimensions are correct…14.52 plus 14.52=29.04..small gap to connect your coax what is so hard to see this???

  • luis colmenares:

    esta muy bueno la información gracia

  • ken, m3zkb:

    adding a extra reflecter will improve the usual bd gain up from ave of 6.6


    hello dear OM, I need an additional element concerning the feed point, what is the dimension (mini, maxi) to respect for an optimum adjustment.
    73 friendly.
