[quote userid="83821" url="~/f/nordic-q-a/110643/lte-cellular-antenna-s11"]Can a high reflection coefficient (say -1dB instead of wanted <-6dB) damage the LTE transceiver or does it have internal protection?[/quote]

What we have that we can share is that the transceiver is able to withstand VSWR 10:1 at antenna port without breaking.

Specs listed here under maximum ratings:

[quote user=""]Is it possible to disable the unwanted LTE bands in FW?[/quote]

Its possible to band lock so that only a select number of bands are used. https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/mob_termination_ctrl_status/xbandlock.html?cp=2_2_0_4_12
