Agree with MyCu (above). It's about 3G and 4G. That's where the thing really helps. Unfortunately, it's not enough to get a stable connection on the train either. But I could have guessed that myself. Stationary great (in the holiday home with a scarce signal).

Can anyone tell me from experience what this 2.5 dB gain brings??? I usually have 2 out of 4 bars on the signal strength at my hotspot and would like to get to 4 out of 4....
Or is the antenna not suitable for this???
