    Hi Team,

     

    Please confirm if in AP 275 do we have any antennas (omni) that can provide the following

     

    1. 6 DBi for 2.4 Ghz
    2. 8 DBi for 5 Ghz

    Yes i checked. I think we have

     

          ANT-3x3-5010
       MIMO, Omni, 10 dBi, 5 GHz, Direct mount to chassis or remoted with N male to N female cable (x3)
     
    But for 2.4 Ghz, its only 5 dBi.
     
    Can you confirm it, also, does (x3) means 3 element antenna ?

    The ANT-3x3-5010 includes three 10dBi 5Ghz omni antennas (2 V-pol and 1 H-pol). The ANT-3x3-2005 has three 2.4Ghz antennas (2 V-pol and 1 H-pol).

     

    We do not have a 6dBi omni antenna, but 1dBi is not going paly a major factor in differences with range and throughput (6dBi versus 5dBi antennas). Our 5Ghz 10dBi omnis will exceed the 8dBi, but will have a more narrow vertical beamwidth. 

     

    The beamwidths of the antennas are usually more critical than just looking at gain, as the gain is not always critical (esp when serving client devices).
