The new Wilson Electronics' 304421 4G Antenna is a robust 75 ohm Omni-Directional Antenna for mounting outside of a building and features up to 4.0 dB of gain. It is designed to receive 3G/4G LTE cell phone signal for all US and Canada carriers from all directions, and should be mounted in the area with the strongest signal. The included mounting hardware allows the antenna to be installed vertically on a pole and improves signal transmission between an amplifier and your nearest cellular signal tower.
