WWAN antennas and Dell Latitude e7380
Good day. I have a question about the WWAN modem on a Dell Latitude e7380 C7TVFH2 laptop. In this laptop I have a WWAN Dell Sierra Wireless AirPrime 3P10Y DW5811e 2242 modem. This modem has 3 "sockets" for antennas - GSM / AUX, Main, WWAN. Unfortunately, in my laptop, the cables from the above-mentioned were not led out from behind the screen - only 2 cables are led out and connected to the Wi-Fi card. Could dear Formum users suggest something about where to look for the above-mentioned antennas, how to get to them, etc. Could the antenna in this model have no WWAN cables at all - what then to do to get such antennas? As far as I know, the modem was inserted into the above laptop not from its news but later. M.2 SSD in WWAN slot will not work on this laptop.

Unless the system shipped with a WWAN card from Dell, the antenna cables are usually not installed. Unfortunately, they're also not sold separately - the only real way to obtain the correct cables is to buy a display assembly that's pre-wired with the antenna.
There are some sellers (on EBay and similar) that offer "universal" antenna kits; how well these work probably varies from seller to seller.

Hi, my name is Joseph. In my experience with dell laptop,s the antenna,s are only installed from the factory is if the pc was configured and shipped from the factory with a wann card. However, I have always been able to reconfigure it by buying a used screen chassis with the antenna,s installed. Simply install them into your system,s screen frame. If you go this route, my suggestion is to take your time doing this job. Most of the antennas are glued in place. But with some time and the proper tools, it can be done

Just to let you know that the wwan antenna for the 7380 can be purchased from more than one seller on E-Bay
