This is Magnetic Mount Antenna having a frequency of 2400 – 2483 MHz and gain of 3dBi. This is very
helpful for signal boosting. Magnetic mount antennas are commonly used
for car and truck applications. The antenna’s magnetic base sticks
securely to the metal of the vehicle. The metal surface of the car acts
as a ground plane to bounce the signal. Since magnetic mount
antennas require a ground plane, they should be mounted on metal.
