The Wilson Electronics 311135 Indoor Wall Mount Antenna is a directional panel that sends boosted cellular signal toward the area where people work, rather than spreading it evenly in every direction. That makes it effective in long rooms, corridors, warehouse bays and offices where coverage needs to reach a specific zone. The white 8.27 x 7.09 x 1.73-inch panel mounts flat on a wall with the included hardware. Gain varies by band: 5.2 dB at 700-800 MHz, 4.4 dB at 824-894 MHz, 4.2 dB at 880-960 MHz, 10.1 dB at 1710-1880 MHz, 10.6 dB at 1850-1990 MHz and 8.2 dB at 2110-2170 MHz. It is vertically polarized, with a 70°/60° horizontal and 50°/45° vertical beamwidth, a 1.5:1 VSWR and a 50 W power rating. The built-in ground plane means no separate reflector is needed. The antenna has a 50 Ohm impedance, and its 9-inch pigtail ends in an N-Female connector for standard building coax. It weighs 1.33 lb. It is commonly paired with the weBoost Connect 4G-X and is a good choice when a dome antenna's 360° pattern would waste signal on walls and unused space.
