I found a used passive antenna on ebay just slightly above the
AliExpress price incl. shipping.<br>
<br>
I'll test that antenna before trying to mod my board, but I hope
support for active antennas can be added. They are really rare &
expensive.<br>

<div>It is designed for passive antenna at the moment (I think
they just took the default diagram for SIM5360). I have asked
them to make a change in production version to switch to use
active antenna circuit. Much easier to find active antennas,
and they are half the price of the passive ones.</div>

<div>The existing boards are fairly easy to ‘mod’, if required.
Seems to be just a 47nH + 10R in series between antenna and
VDD (3.xV).</div>

<div>Or just use a passive antenna. Something like this?</div>
