How it works:

The external antenna receives the GSM , 3G and 4G signal from all operators in the area. 

The signal is sent inside the building via a 12Mt cable to the StellaBoost where it is amplified and transmitted around the room by the indoor antenna.

800, 900, 1800 and 2100Mhz gets amplified with this booster.

This ensures you are covered for all voice and data.

Perfect for small offices, apartments, basements and other small areas where there is no signal.

The StellaBoost L4 has a new touch LCD screen. This allows you to control the bands more precisely.

You can swith on /off any particular band, turning your booster into a pure 4G booster or parhaps only a voice booster.

You can also attenuate and balance the bands as you see fit.


The StellaBoost L4 boosts 4 bands.

  • B20 (800Mhz) is great for rural locations and fast 4G speeds
  • B8 (900Mhz) : This option is great for voice calls in rural locations.
  • B1 (2100Mhz) : This option is great for slow but stable 3G data speeds and good quality calls, in urban locations
  • B3 (1800Mhz): This band is great for 4G data speeds in Urban locations.


The outdoor panel antenna is installed outside your building where you have at least 3 steady bars of steady mobile signal. (5-6 even better)
The kit is very easy to install and requires no further attention once you plug it in. It seamlessly amplifies the mobile signal from outside where there is good signal, and sends it around your house.
