If you have not had a chance to see the new Cisco Catalyst antennas for Catalyst 9130AXE access points, here are a few photos of the C-ANT9103 antenna for your reference.
Size, weight, mounting options
The official installation guide provides all this information and much more.
The optional access point “pocket”
Optionally, you can order an AP + antenna collocation “pocket”, which the Catalyst 9130AXE slides nicely in. It is aesthetically pleasing it, and all it takes to install the AP and antenna is a single mounting bracket. You don’t have to worry about mounting the access point and antenna separately. This drastically simplifies temporary deployments – just think about Cisco Live for example.
Please always refer to the official Cisco documentation for the latest information and package contents.
