The Wideband Directional Antenna 50 Ohm (311233) is the building-exterior donor antenna Wilson engineered for the WilsonPro Pro 710i industrial-grade cell signal amplifier. It is also rated for high performance with weBoost cellular boosters. It covers seven segments from 617 MHz to 2700 MHz, including low-frequency 5G Band 71. It also works on the LTE, CDMA, GSM, UMTS and AWS cellular bands worldwide for voice and data. Because it is directional, the antenna focuses on the tower you point it at. Peak gain ranges from 4.8 dBi in the 617-698 MHz band to 8.3 dBi at 1710-1880 MHz. Front-to-back ratio reaches 20 dB in the mid bands, and efficiency is above 68% and 75%. The antenna uses vertical polarization, 50 Ohm impedance and an N-Female connector, and handles 20 W of maximum power. The antenna is built for year-round outdoor use. An aluminum radiator sits inside a sealed, UV-stable white ABS radome that is rugged and waterproof. At 11.5 x 8.2 x 2.5 in and 1.76 lb, it is compact enough for rooftop and wall-mast installs. The included tilt/swivel mast bracket clamps to pipe up to 2 in in diameter and lets you point the antenna toward nearby Band 71 towers. The kit contains the antenna plus a pole mount and hardware. The unit is assembled in the USA and carries Wilson's 2-year warranty. A manufacturer spec sheet with radiation patterns is available for RF planning.
