I had the same idea as booty and pondered it around, as the logic seems to make sense until it is time to construct it.

the 5% longer rule for reflector actually puts it 5% lower in frequency resonance compared to the driven element, it would be a PITA to build a yagi like that.

On the other hand I also pondered a ground mounted two element vertical array for the lower bands, driven and director. .625 driven element then a 5% smaller director spaced .25 wl in front of the driven element, might work good for 40 meters. I thought about it, but will probably never experiment with it.
I like it when Booty posts the questions about antenna ideas, makes one think outside the box

[QUOTE="wavrider, post: 327813, member: 9893"] I had the same idea as booty and pondered it around, as the logic seems to make sense until it is time to construct it. the 5% longer rule for reflector actually puts it 5% lower in frequency resonance compared to the driven element, it would be a PITA to build a yagi like that.
