    Hello all,
    My friend kd9ick and I are wanting to make 2m/70cm hex beams. I've done some looking around and I can't find dimensions or anything. I don't know how a hex beam works or how to calculate wire lengths. Any help with construction and dimensions would be greatly appreciated

    While you could scale things down for VHF/UHF hexbeams it would be a lot easier to make Moxons instead; MoxGen will give you all the numbers you'll need.

    Better F/B and about the same or more gain, too.

    A two or more element Yagi will beat a hexbeam in forward gain and front-to-back, so why bother? So will a Moxon.

    Are you trying for more compact, like for RDF?

    our goal was to have directional antennas to point at each other and thought some small 2m hex beams would look cool but it sounds like that may be impractical

    A moxon for 2M is about 2 1/2' x 1', pretty small. I made some one years ago but later decided that a 3L broomstick yagi better suited my needs.

    I can't think of any practical reason to construct a 2m/70cm Hexbeam antenna.

    For operating from a shower stall, glass elevator or Porta Potty a 2M/70cm hex beam is just the ticket! Better to build the Traffie style rather than the TXQ wideband hex as it has the smaller turn radius...

    Way too many other options for the freq. you are talking about.
