GSM Antenna, model GA2/GA1, L-Type/Straight that strengthens your GSM connection significantly. This increases the signal strength, the signal stability and thus the transmission rate of the connection. Provides a 2.5 dBi gain and works with 900-1800 MHzfrequency. The antenna uses an SMA Male connector compatible with network devices that use SMA Female connector. Can beused with various types of modems, access points, terminals, routers and other devices. Omnidirectional, wireless transmitting or receiving antenna that sends or receives radio frequency (RF) and electromagnetic fields as well in all horizontal directions in a flat, two-dimensional (2D) geometric plane. Manufactured with high-quality materials to guarantee a higher speed and higher fidelity data transfer.
