LTE M1 Antenna Peak Gain

I am starting to find sourcing for a small antenna for the LTE M1.

To stay within compliance of Particles approvals, whats the peak gain the antenna can have to stay within approval limits?

I don’t believe the antenna selection has been finalized for LTE. Note that the Taoglas penta-band PC104 antenna used in the Electron and E310 probably can’t be used because one of the LTE M1 frequencies is 2600 MHz, higher than that antenna supports.


@mohit Just wondering if there has been any development in what antenna is being used for the Eseries LTE module?
