[TowerTalk] minimum XM-240 stacking distance?

[W0MU Mike Fatchett]

The further the better.  If you put the 40 90 degrees off it will help.  
Otherwise you will have some interaction on 15 at 10 ft. I have the same 
arrangement.

Look at turning the XM240 into a Moxon and get rid of their capacitor 
match.  The extra element really helps.
