Oops, Sorry Brett :-o

This is an indication that I should get some sleep ;-)

Lets try again...

Hi,

Does this mean I better not have two antenna mounted on the same mast? 

This is what I try to achieve...

I have setup and in testing a redhat 7.3 box (thanks to Martin Pot for
his info :)) with 1 cabletron cards inserted into PCI cradles and 1
Compaq WL-200 PCI card. 

WL-200 will serve as an AP and will be connected to an 8dbi Omni
antenna.

Cabletron will be use for point to point (WAN) link and will be
connected to a 24dbi parabolic mesh (similar to conifer or ex galaxy)
antenna.

Please be gentle on this newbie  ;-)

Cheers
Rob
