A hex beam antenna looks like the loops are a continuous loop but they are not.  The driven/forward  elements make an “W” shape dipole  with the feed point on the center post.  The rear element has a insulated Kevlar string separating it from the driven element with a small gap. So you can see it is not an continuous loop  of wire.  The sizes of the loop goes from small { 10m } to the larges loop { 40m } with each loop doing a different band.  Our antenna will cover 10, 12, 15, 17, 20 ,40 meters.
