The WilsonPro 311228 High Gain LPDA (log-periodic dipole array) Antenna is the outdoor donor antenna for commercial WilsonPro signal booster systems. It mounts on a building exterior and points at the nearest cell tower, concentrating gain in that direction to pull in the strongest possible signal for the amplifier. It works on worldwide cellular bands for voice and data, including LTE, CDMA, GSM, UMTS and AWS. Peak gain is 12.0 dBi at 698-806 MHz, 12.0 dBi at 806-960 MHz, 12.9 dBi at 1710-1880 MHz, 13.1 dBi at 1900-2200 MHz and 11.2 dBi at 2200-2700 MHz. Half-power azimuth beamwidth ranges from 60° down to 38°, and elevation beamwidth from 46° to 30°. The antenna has linear polarization, VSWR below 2:1, a 50 Ohm impedance and a 50 W maximum power rating. It is built to last outdoors. The aluminum radiators are rugged and waterproof for all-weather operation, and the antenna is rated for 130 mph wind. It is 44.0 inches (111.7 cm) long and weighs 3.5 lb (1.5 kg). The included tilt/swivel bracket fits 1.5-2.0 in. (3.8-5.0 cm) pipe or mast for precise aiming. The connector is N-Female, and a spec sheet is available. The manufacturer provides a 2-year warranty.
