[TowerTalk] Stacking 20m and 15 meter mono banders on the same mast.

All:

Was thinking about replacing my existing multi-band HF Yagi with 4 element 
M2 monobanders for 20 and 15 meters. Specifically the 20M4DX and the 15M4DX. 
The antennas would be mounted on the existing tower on a 20 foot mast.

The first thing that comes to mind is stacking the antennas with enough 
space between them to avoid any detuning. The other question is where to 
mount my existing six and 10 meter Yagi's to avoid the same.

The plan is to mount the 20m Yagi at the botom of the mast and the 15m Yagi 
about 10 feet above. The 10 and 6 meter Yagi's will have to be close at the 
top of the mast. Not sure if this is the best way to go.

Any comments on how M2 mono-banders compare to others manufacturers in terms 
of performance, workmanship and quality components would be appreciated. 
Another concern is consistent gain and F/B accross the band. My main 
interest is CW and the M2 20m Yagi looks like it can be "peaked" for the 
lower end of the band.

Thanks,
