@efjay I used Dell E7x70-something cover indeed. In USA, one can easily source an LCD cover with correct antenna in some online stores selling parts for business PCs. All vendors used the very same antenna module (10041R) in all WiGiG devices based on Intel implementation, so you can be sure it will fit. Some vendors add a plastic bracket to antenna so that cable doesn't come loose from vibration - it is easy to DIY in case you need it. Cables, on the other hand, vary in length; in my machine, cable is noticeably longer than it should be, but I can live with it and it generally does not create any inconvenience except when the hinges need to be removed for some reason. Here's a listing on eBay; the cable might be long enough if you're lucky. FWIW I have a spare MHF5-MHF5 cable, from Thinkpad t460s, and may consider selling it if you have no luck sourcing long enough cable elsewhere - but part of outer layer is stripped (it was soldered to WLAN antenna, sharing GND or something like that), so you'll have to repair it before using.
