    Hey there Colin! This video inspired me to look into the hexbeam design. (I've been a ham since the early 80's but not much active since late 80s...getting into it again as I near retirement).
    Anyhoo, I was looking G3TXQ's (SK) information, and noted the troubles and degraded performance when trying to include lots of bands (as you plan to do) due to coupling between elements of adjacent bands.
    So here's an idea for an experimentation minded bloke like yourself: What if you were to alternate the driven and reflector elements on each end of the beam, making pattern for every alternate band "backward" on the framework?. Shouldn't be so hard to adjust for in operation with just two pointers on the mast labled with the bands they corrispond to.
    While this would still put the driven elements in close proximity to the adjacent reflectors, the hex-beams asymetric element shap means they only paralell(ish) for part of thier length.
    The hexbeam is rather well suited in being able to pull such a stunt, as the feedpoint remains in the middle, unike a classic two element yagi.
    There are six possible directionalities, so there might even be something to be gained by turning each set of elements 240 degrees with respect to the next lower band. This would minimize the paralellism of any of the elements on adjacent bands.
    Yes, I do think to much...is that a bad thing?

    Really great project Colin - thanks for sharing this. Using tent poles is genius as they are readily available and very strong. I admire the way you are using easily available stuff to make it. Have had a Hexbeam for a long time - really interested in the specifics of the wire clamps you sourced as that is a tricky problem to solve (I built my first heavy-duty hexbeam a few years ago using the K1KIO site but now have one from Ant in Wales). Looking forward to the next video mate. 73

      Thanks Tom. I don't see the point in showing folks how to build something they cant get parts for. Any part of this can be replaced super easy.

      @@nandrews8412 Actually that's not quite correct. There are many 3d printing services that you can send a design to and they will print the parts for you, and there are many vendors on places like Etsy that will sell parts for anything they can make a profit on. Most public libraries have 3d printers for public use, and anyone with kids in school probably has access to them indirectly, and the friend of a friend probably has one as well. 3d printers start at $100-200 so there's little reason not to have one. They provide better solutions than off the shelf parts for many things. The clips and brackets you are having to modify or find something that sort of works for can be made better with 3d printing. Your designs can be improved with 3d printed parts. Design it both ways and see. Make what you need instead of making do. Makers should have good tools and the 3d printer is the best tool I have ever purchased. Also good for custom project and balun enclosures.
