How it works 

The line compensator equalizes losses in the aerial cables. The line compensator ensures the full transmitting and receiving power of the mobile phone is available at the aerial. The use of the line compensator increases the transmission output to the GSM antenna to a maximum of 2 watts. Increasing the transmission power extends the range within the GSM mobile phone network.
