When comparing different signal boosters, it is important to look at the ‘gain’ that the antenna offers. Antennas with higher gain will produce the biggest improvements in signal strength. The antennas with the highest gain tend to be 'directional'.

Clip Antenna are the most common type of signal boosters and typically offer a gain in the region of 2db, High Gain Directional Antenna offer 8-10db while the external directional Antenna offers 10-12db.
