2G 3G 4G LTE indoor antenna GSM 3G dual band booster antenna 5dBi Omni antenna

Feature: 1.The omnidirectional antenna transmits signals in all directions. Both the front and the back can receive signals. 2.The directional antenna is like a bowl-shaped reflective surface behind the antenna. The signal can only be transmitted to the front, and the signal to the back is blocked and reflected by the reflective surface. To the front, the previous signal strength is strengthened. The main radiation range of a directional antenna is like an inverted, less complete cone. Attention: This is an panel antenna only. It doesn't work alone. You need a Signal Booster/Repeater to work with this.
