High Gain antenna for Cisco 9120AXE

[tlindley]

For my Cisco 9120AXE access point, what high gain external antenna is recommended to get the WiFi 6 signal through plaster walls and ceilings?  The original 4 post antennas are not getting the job done.

I have a Cisco Aironet 5-GHz 14-dBi 2-port directional antenna available.

Has this site done site survey, if not consider doing site survey ?

Some reference antennas and their signals :

Cisco Catalyst 9120 Access Point Deployment Guide and scroll down to the Approved antennas Catalyst 9120e section.

IMPORTANT:   Get a wireless site survey done before purchasing the antennas.

You can also look at third-party antennas such those from AccelTex.
