Yoga 370 WWAN Antenna retrofit

Hello experts,

 

I am looking for the possiblity to upgrade my Yoga 370 (TYPE 20JJ-S01S1A) with WWAN, since it has no antennas factory installed. Can someone tell me the FRU number and potentially give me some hints how to install them?

 

Best regards.

Re: Yoga 370 WWAN Antenna retrofit

@dctigga try your adapter with your WLAN antennas first, if it will work fine - then you can save a small fortune by getting 2 more WLAN antennas. Here is how I installed antennas on its sister model, 260. If you're dead set on getting native WWAN antennas - which will be hard & expensive - correct FRU is 01HY235.
