No it doesn’t. When tested, the Huawei CPE PRO 5G router (the only full-size 5G router currently available) together with a Poynting 4G-XPOL-A0002 Antenna simply decreased my 4G speeds by 95%. It basically did nothing to improve the signal past the speed obtained with no antenna at all.
Note that there’s no 5G signal out here so who knows if that would have worked. I was only testing to see how the 4G performance was, and it certainly didn’t work at all with this antenna.
Time to go back to my trusted Huawei B525 which has worked very reliably since I first installed it.
