Re: AP-ANT-38: Cross or Co Polarization & Gain

Co-polarization would require all antennas to have the same orientation.

Re: AP-ANT-38: Cross or Co Polarization & Gain

Sorry, In your early post, you said "All Aruba panel antennas are cross-polarized. All others are co."

 

But same orientation type is panel anteena, maybe I am wrong?

Re: AP-ANT-38: Cross or Co Polarization & Gain

What I think he meant is the panel antenna is built of three different antenna elements with different polarization.This is why Aruba refer to them as cross polarized instead of if you use three identical dipole antennas, which they refer to as co-polarized.

Re: AP-ANT-38: Cross or Co Polarization & Gain

Good thread. For clarification, with respect to selecting appropriate "External Antenna Polarization" parameter for each frequency, if the antenna used is from Aruba we should select "1-Cross-Polarized"? (pic attached)

 

Running AOS 6.5.x now, recently upgraded from AOS 6.4.x. In 6.4 there there was no such parameter. The default appears to be "0-CO-Polarized".

 

We have thousands of AP-324s deployed. Most use the 1W antennas. believe the antenna orientation is 45 degrees away from the AP.

ANT-1W (direct mount omni dipoles) should be oriented vertically and all parallel, to provide matching coverage patterns.

Re: AP-ANT-38: Cross or Co Polarization & Gain

Yes understood! We're aware of that and are working to hopefully correct it. I'm more interested in knowing the correct setting of "External Antenna Polarization".

Re: AP-ANT-38: Cross or Co Polarization & Gain

Hello, 

 

Same question with ant-16, what we should use :  cross or co-polarization in GUI ?

Re: AP-ANT-38: Cross or Co Polarization & Gain

Multiple parallel oriented ANT-1W antennas are co-polarized.

Same is true for the elements in ANT-16.
