Outdoor LTE antenna for C921-4PLTEAU


Hi all, i'm looking for an outdoor LTE antenna that would fit on the C921-4PLTEAU, with similar characteristics to this: XPOL-002-5G.


It's not so easy to find ISR900 LTE antennas, other than the standard indoor dipole: LTE-ANTM-SMA-D.

Any ideas where to look for this with Cisco?

Haave you checked Panorama antennas like this or this?

Thanks, but no, it must be from Cisco.

You could also look at (which doesn't mention C9xx) and then check specific data for any of those parts which you like the look of.
