Hi
I have a situation of low GSM signal indoor and I need to amplify it
I have seen some boosters availble but I wanted to know is it possible to amplify gsm signal using active GSM antennas ?
I have some active antennas gor GPS and GSM and they have LNA inside
my plan is to use these antennas and supply them with dc power supply

have you any experience on this ?

thanks in advance
