The Wilson Electronics 304412 4G Dome Ceiling Antenna is the inside antenna in a building signal booster system. Mounted on the ceiling, it takes the amplified signal from a weBoost or WilsonPro booster and spreads it through the room in an omni-directional, 360-degree pattern. That makes it well suited to general coverage in open-plan offices and commercial interiors. The manufacturer states that it works for all U.S. and Canada cell carriers. The antenna covers two wide frequency ranges: 698-960 MHz at 2 dBi and 1710-2700 MHz at 4 dBi. It is vertically polarized, with a 60-degree vertical beamwidth, VSWR below 2 and a 50 W maximum input power rating. A built-in ground plane and DC-ground lightning protection are included. A 300 mm (11.9 in.) pigtail ends in an N-Female connector for standard 50 Ohm building coax. The white ABS radome measures 7.3 inches (185 mm) in diameter by 3.3 inches (85 mm) high and weighs 0.63 lb. It is rated from -40 to 65 °C and is RoHS compliant. For systems built on 75 Ohm coax, Wilson offers the F-Female 304419 version. The 304412 carries a 2-year manufacturer warranty, and a spec sheet is available.
