The multi-polarized 4x4 MIMO sector antenna designed for radio hardware which can effective use 4 Rx/Tx radio channels. Antenna consists two independent sections, each one is for generating orthogonal polarization planes: HV and +/-45 deg.
The polarization suppression for each sections is as high as the crosspolar suppression and port-to-port isolation, while the suppression between polarization planes which differ by 45 deg. is 3 dB and is restricted by theory.
Please take it into account at the planning stage of the wirelles lan network.

As you can see, the TetraAnt 5 60 18 XHV has the VSWR better than 2.0 in the whole 5.1 GHz to 6.2 GHz frequency range.
Please note that in the band 5.1 - 6.1 GHz the VSWR is better than 1.4 More about this type of measurement can be found in the tab Resources.
The horizontal red line shows VSWR = 2.0, the smallest vertical scale is equal to 0.2
The isolation is no worst than 30 dB between ports 1 and 2 or 3 and 4, but is as high as 50 dB between ports 1/3, 1/4, 2/3 and 2/4. More about port-to-port isolation.
Do not confuse this values with the polarization suppression. The port-to-port isolation is not the same like the polarization isolation. As stated above the polarization isolation for polarization planes which differ by 90° is as high as the port to port attenuation, while those differs by 45 deg. are suppressed by 3 dB.
The horizontal red line shows attenuation = 30 dB, the smallest vertical scale is equal to 10 dB
