MIMO antenna: port mapping, alignment & cable loss
Preface Modern LTE and Wi-Fi routers promise “MIMO performance,” yet the hidden variables behind that extra throughput are mostly mechanical—how ports are paired, how antennas are aligned, and how much loss hides inside each coax run. Even a perfect chipset can underperform if one cable path adds 1 dB more loss than the other or if the antennas face different azimuths.
