Been having some issues with 2 aironet 1200's.. Now I am thinking
perhaps we are just asking too much out of these devices. We have 2
yagi antenna's mounted outside on the roof of both buildings.. Just
wondering if anyone has any thoughts at to what type of range we
should be getting.... The buildings are in an industrial area but the
antennas have line of site.

lot of factors here - distance between access point and antennas, type
of cable used ( low loss ?) , power gain of yagi antenna, installation
techniques ( ie. proper sealing of outside cable joints, etc, etc

Fresnel volume? See
<http://www.cisco.com/en/US/prod/collateral/wireless/ps7183/ps469/product
_data_sheet09186a008008883b.html>. There's a fancy spreadsheet you can
download from there which might help you work out what's possible.
