Zte Mc801a Antenni -

| Scenario | Before (internal only) | After (external + internal) | |----------|------------------------|------------------------------| | Good signal (RSRP > -85 dBm) | Minimal gain | 5–10% throughput gain | | Medium (-95 to -105 dBm) | Unstable | +5–15 dB SINR, stable | | Weak (-110 to -120 dBm) | Frequent disconnects | Can become usable, but not guaranteed | | No line-of-sight | Poor | Directional antenna can help if tower is known |

If external antennas don’t help:

Some users solder U.FL to SMA pigtails directly onto the PCB’s 4 antenna pads to get 4×4 external MIMO. This: zte mc801a antenni
