[Towertalk] Anyone modeled A3S and A3WS on same mast?

[Maury Peiperl]

Greetings towertalkians...

I've got an A3S and A3WS (with 30m attachment) and wonder if anyone has 
modeled them (with or without the 30m attachment) on the same mast at 
different spacings.  Cushcraft says only to keep them as far apart as 
possible, which in practical terms means I have to decide whether to buy 
a longer mast.  Does anyone have actual data (or failing that, anecdotal 
evidence) for what a reasonable minimum spacing is between these two 
beams?  I would like to avoid putting the beams at right angles if 
possible.  The lower beam (A3WS) will be at about 47'.

Many thanks for any help you can provide.
