One AIR-ANT2547VG-N (omni) and one AIR-ANT2588P3M-N= (directional). I Know, they are both dual band. I will rephrase my question. Can I install both of them on a single 1562E. I need to cover an omni area with the AIR-ANT2547VG-N and a downhill steep path with the AIR-ANT2588P3M-N=. If both work as dual band it will be optimal. It is acceptable though, if one needs to work at 2.4GHz and the other at 5GHz.
