single band vs double band / omni vs dipole

[mirehteshamali]

Hi

plz help me with the following

1) differecne between double band and single band antenna

2) does 1040 1140 1240 1260 access point support RP-TNC Connectors (antenna).

can i select these access points with any antenna wth RP-TNC Connectors

3) what is the difference between omni and dipole antenna

    (they both have circular coverage )

Regards

Hi,

1) differecne between double band and single band antenna

ANS - Single-band Antennas use a 2.4-GHz band and dual-band antennas use both the 2.4 GHz and 5 GHz  band.

2) does 1040 1140 1240 1260 access point support RP-TNC Connectors (antenna).

can i select these access points with any antenna wth RP-TNC Connectors

ANS - 1040 , 1140 are integrated antennas and does not have RP TNC connectors.. the 1240 and 1260 comes with RPTCN connectors to connect the antenna.

3) what is the difference between omni and dipole antenna

    (they both have circular coverage )

ANS - The below link will provide the depth info regarding different antenna.

what is the difference between omni and dipole antenna

An omni-directional antenna means that if you hold an antenna and point the tip to you, the footprint of the signal goes around.  It's like a bullseye.  This is called the horizontal azimuth.  HOWEVER, the vertical azimuth or the footprint when it's standing up is vastly different.  Look at the product documentation of the Cisco dipole antenna and you'll see.

A dipole antenna can also be known as a pogo-stick antenna or a disco stick (my favorite).  Mostly dipole antenna is omni-directional.
