Re: improve gsm antenna

You could try using an antenna with higher directivity. Consider a horn antenna, yagi-like antenna, dish reflector, ... The higher it's directivity, the further your range reaches.

Yet I don't know whether these things are on the market for GSM.

Just to have in mind that in GSM (due to the time delay) the distance from the Base Station can be maximum 35 km.
