This one is almost 7 ft long and you'd have to build it yourself, but it might work for you.  For backpacking use, the boom and mounting clamp could probably be lightened up a bit more.  It is pretty easy to unintentionally bend the elements in rover use....backpacking would likely be worse.  The balun, as shown, has not been tested above 20 W or so - not sure what power it would take.

WA5VJB also has a shorter (5 ft) 11 element wood-boom design at https://www.wa5vjb.com/yagi-pdf/cheapyagi.pdf .
