The weBoost 50-Ohm Wideband Directional Antenna (314411) is an outside donor antenna for homes and buildings in weak-signal areas. As a directional Yagi, it concentrates its gain toward a chosen tower rather than listening in every direction. This lets a cell signal booster pull usable signal from towers that are far away. weBoost designed it for use with its residential cell signal boosters. It is compatible with all US carriers and supports multiple devices through the booster. The antenna covers 700-2700 MHz. Published gain rises from 7.3 dB at 700-800 MHz to 10.6 dB at 1850-1990 MHz and 10.4 dB at 2110-2170 MHz. It is a vertically polarized, 50 Ohm antenna rated for 100 watts, with an N-Female connector for coax cable fitted with N-Male connectors. If you use a 75-ohm amplifier, it needs the appropriate connector to join the outside cable to the amplifier or antenna. For installation, a tilt-swivel bracket and aluminum U-bolt mount attach the antenna to an exterior wall, antenna pole or rooftop vent pipe. It accepts pipe 1.25 to 2 inches in diameter, and mounting hardware is included. The antenna is 11.42 inches long, weighs 3.31 lbs (1.5 kg) with its mount, and presents a 465 cm2 wind surface area. The anti-UV plastic housing resists sunlight, water and debris for all-weather use. The 314411 is also the wide band directional outside antenna supplied in WilsonPro Enterprise 4330 kits. weBoost includes a 2-year manufacturer's warranty.
