How the dual band signal booster works:

The StellaRoomGW dual band signal booster is suitable for installations where you have a good external signal, and you want to amplify 1 or 2  rooms in your house or small office.

In modern buildings, the double glazed windows and foil backed insulation in walls, stop the mobile signals from entering the house.

With the StellaRoomGW signal booster, the external antenna receives the 3G and GSM signal from all operators in the area.

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

Both 900Mhz 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.

This booster kit includes

  1. 1 StellaRoom 900/2100 signal repeater
  2. 1 outdoor Panel antenna
  3. 12 meters of SD240 cable
  4. 1 12v power supply

Quick install guide

  1. We recommend doing a "loose" install first, so that you can test where best to place your cables and antennas.
  2. Install the outdoor panel antenna in a location where there is good mobile signal. (usually this is your roof).
  3. Using the supplied 12m cable, run it down inside your house to the StellaRoom  repeater.
  4. Attach this cable to the repeater and plug in the power supply.

The frequencies explained:


900Mhz is used for the GSM network. GSM is a robust standard used by your phone and the operator’s base station to transmit voice signals. It has been about for a long time which is a testament to how successful it is. All phones, including the older “non-smart” phones can use this standard. 900Mhz is a relatively low frequency that is excellent at propagating through the countryside. It is most likely that this frequency is available outside your house (Can you make calls outside your house?). It also uses much less power then 3G or 4G. ie, your phone battery lasts longer!


2100Mhz is used by all mobile operators for the 3G network. This is available in all cities and offers very fast data speeds. It is also available in many parts of the countryside but you should always check outside your property to see if you can receive this frequency on your phone. Generally, if you can browse the internet on your phone outside your property, it is likely you are on 2100Mhz, 3G.
