But I thought that 28dBi was the largest dish you could put into an
802.11b link under FCC rules.  Oh wait, [email protected] might not be in
the US :-).  A 40dBi dish is possible, but I'd imagine that it would
have such a tight beam that it would be very very hard to properly aim
and secure.  It would also be so large that the wind would become a
major factor in signal quality due to deformation effects...
