I have a K4KIO for the ham bands. Be aware, the most common multiband hexbeams (for ham) you will find have a fairly narrow bandwidth on the 10m element. They do not perform well on 11m at all. Not just because of VSWR, but the lobes do funny things and they loose much of their directivity. If you build or buy one for 11m and want it to work on 10m also, the same limits will apply.
For 11m, you would need to modify the 10m element and retune, or make one specifically for 11m. Because the elements do interact with each other somewhat, it can be interesting to get them resonant everywhere you need.
For a directional antenna with gain and a small footprint on 11m use, I would personally get a 3el yagi over a Hexbeam, unless you really want a multi-band antenna. A 3el typically has a lot better F/B ratio and is usually much better off the side too. A hex is pretty broad in comparison.
But building a monoband 11m hex could be a fun project if you are keen, or you could buy one of course (
@Big Kahuna thats a nice looking design. Good price too).
