Mikrotik Chateau LTE12 External Antennas

Hello everybody,

My provider sends me preconfigured routers Mikrotik Chateau LTE12 for my clients.
The external antennas are set to present mode, but I don't install them.
Can that damage the router?
Thanks.

I would say that IF they were needed, they would be in the package (but they aren't):
https://mikrotik.com/product/chateau_lte12

The RouterOS on that model should have a setting that is related, it is normally:

/interface lte settings
set external-antenna=auto

Possible values:

This setting is only available for “Chateau” routers, except for Chateau 5G versions.
auto - measures the signal levels on both internal and external antennas and selects the antennas with the best signal(RSRP).
both - both antennas are set to external
div - diversity antenna set to external
main - main antenna set to external
none - no external antenna selected(using internal antennas

If you leave it at "auto", it is fine without external antennas.
