Operator compatibility:

The amplifier HI20-5S improve your 3G, 4G and GSM reception with following operators :
• Orange
• Foreign operators work on GSM (900MHz) – 3G (2100MHz) - 4G (2600MHz) frequencies.


2000 m2 of covering around the interior antenna included in the pack.

Installation :

Simple, and easy to install ! You juste have to fix the exterior antenna in direction of the relay antenna of your operator ( relay antenna map) and to connect the GSM/3G/4G booster to a 220V electrical outlet. The external antenna must simply be separate by 5m of the internal antenna.
