I am using GSM MODEM provided by sim300 and i have no clue regarding the antenna specifications of the antenna used in this modem.
In the pdf file it is just mentioned that the module has 50db antenna connector.I do not know anything about this antenna connector and in what way it is related to the GSM modem antenna.?
