Direct Connected amplifier for EU

[mldowling]

Hello @wavemag,
Rater than rewrite these previous post from @kevin and myself, here are two quotes on your question.

@mldowling

Our professional advise is DO NOT use any inline boosters connected to your LTE modem (this is regardless of who makes the modems or boosters) focus on using a better antenna solution. Even with one booster per antenna connection, they will still cause more problems than they solve, not to mention most of them put way to much RF power back into the LTE modem and are likely to damage the chip set within the LTE modem (this sort of damage is not covered by any form of warranty).

@kevin

You shouldn’t hook a repeating amplifier directly to a cellular modem. The gain coming off of these amplifiers is well over what an embedded modem can tolerate and you are likely to burn the modem out in a worst case

Have a read through the two full posts for more information.
Happy to Help,
