This is a GSM antenna with SMA connector. Its magnetic base can be easily adsorbed on the surface of ferrous material. The working frequency 900-1800 MHz meets the most requirements of GSM application. This Antenna extension cable uses 174 pure copper material, which has less impedance than the other cable. The antenna signal gain could arrive 2.5dBi. Its compact size makes it easy to carry and use.
