Cisco’s Wi-Fi 6E outdoor CW9163E access point is an external antenna only model. It requires either 4 omnidirectional dipole antennas CW-ANT-O1-NS-00, or directional antenna which I cover in this post separately.
The CW-ANT-O1-NS-00 antenna ships in a little recycled paper bag and it includes a single antenna. Please make sure you order this CW-ANT-O1-NS-00 SKU four times and populate all N-type connectors of the AP.

Here is a detail of the label.

If you are wondering what its dimensions are, here is a standard UK banana for scale 😊

Joking aside, the antenna is about 23 cm long.

And its thickest point measures 2,8 cm.

Finally, here is the AP with all 4 antennas attached. The whole set is about 65 cm tall.
