[TowerTalk] antenna spacing

[WI8W]

My 50 foot AN Wireless tower was installed last weekend and sometime in the
near future (probably when it is snowing like crazy outside) the antennas
will be installed.

I am planning on installing the following

Cushcraft A3
Cushcraft A50-5
Cuchcraft A144-20T
Cushcraft A719  432 yagi

guess you could say I am a Cushcraft fan.

I have 15 feet of mast above the thrust bearing to play with.

I am looking for suggestions on spacing these antennas.  I might be willing
to sacrifice the 2 meter or 432 if necessary

thanks
