[MLB-WIRELESS] AP that you can connect two directionals to??

[darrend at ndpgroup.com.au]

Paul, yes this is possible... you could use 2 high gain directionals with 
a power divider/phasing harness on one ap... or even a normal card running 
in ibss mode aswell....(hmm... maybe roger can confirm this)  Only 
drawback is that traffic is mirrored on both sides of the link... eg acts 
more like a ethernet hub. This may be fine if max performance is not 
required. If distance is also not an issue, then a single omni may also be 
sufficient.
So, put simply... there are many ways around this problem without using a 
2 card AP.

Kambrook have a new kettle due for release this christmas that will do all 
this aswell!

Hi all,

If you take an AP, rip out the omni and add one wire connected to two 
directionals (obviuosly pointing in different directions), will it still 
work as an AP?  I.e. will it then act as a relay?  OK. if the answer is 
yes, then if you have enough strength then leave the omni in place and 
point directionals at it...  let the AP do the work as it were...  why 
would you need dual antennaes???  I don't understand...
