Hello Gary,

I am sorry to hear that you will not have more room for 6m, but 
certainly understand your situation.  Sounds like you sure have a 
wonderful tower installation that will serve you very conveniently for 
many years to come!

I think your decision to go with a single good yagi is a certainly a 
very good one.  For 6m DXing, I am a proponent of the K5CM philosophy of 
trying to put up the biggest single yagi you can, up as high as 
possible.  I would suggest the 50' long 6M9KHW as a very good single 
yagi that meets your gain objectives.  As you know, I use four of them 
here, and am very happy with the construction and performance.

I would also suggest that it be on the bottom of your stack, so it is 
not shielded from ground reflections by a larger HF beam below it.  If 
you do decide to install an HF beam below the 6m antenna, I would 
recommend turning the HF yagi 90 degrees to the rest of the stack, so 
your higher yagis can see down through them.  The single yagi should 
perform well at that height with three good ground gain lobes, providing 
you coverage for incoming propagation at a variety of angles.  In 
addition, the antenna should be mechanically superior than a stack of 
large yagis and be simpler to cable electrically.

Good luck and VY 73, Lance
