Many users assume these are standard SMA ports (like those found on most routers) and purchase standard antennas, only to find they don't fit. The TS-9 standard is smaller and requires a specific adapter or cable. Furthermore, a common misconception is that these ports support 5G. In most firmware configurations for the MC801A, these external ports are . This means plugging a 5G MIMO antenna directly into these ports may not yield the 5G signal boost you are hoping for. zte mc801a antenna mod
