If I understand your questions correctly you want two antennas on same APs pointing on different direction ?
If this is the case , answer is no .
Two Antenna connector is for the Diversity and multipath operations .
To seperate the two antennas on the AP to increase the coverage is
self defeating .
The receiver only listens to one antenna at a time , so while it is
listening to one antenna ,
it's deaf to the other , therefore no coverage area there , and
vice versa . In addition there is till loss in the rf cables which
reduces the effective range of the clients to the Ap
The best way to increase the coverage is to conduct the site survey to
determine the RF coverage and put the Ap in the appropriate areas .
* Distance is not critical . The purpose of the diversity is to overcome
multi-path reflections , therefore so long as the antenna are 1-8 feet
apart or so that would be fine
You don't want the antennas really close ( under 6 inches or so)
because they would tend to " play off each other " causing
the pattern to start to become directional when perhaps that's
not desirable
There is no "true optimum distance "
* Diversity means two different antennas covering the same area but from a
slightly different perspectives .
The angle of the antenna is what is covered by each antenna , but since
they are desinged to cover the SAME area .
