How the StellaRoom900 signal booster works

The receive antenna is installed where you have a good signal.

This is usually on your roof, but can also be outside a window.

This antenna will receive the gsm signal  and send it down the coaxial cable to the gsm signal booster which is placed in the room where you want coverage.

The gsm signal booster then amplifies this signal and transmits it into the room.

Your mobile phones and laptops nearby can now communicate with the improved gsm signal.

When a mobile phone transmits during a call, the signal is received by the booster, amplified, and then transmitted back to the network base station via the panel antenna.

The StellaRoom900 gsm signal booster is designed for residential use, with coverage for 1-2 rooms.

This booster kit includes

  1. 1 StellaRoom900 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!
