The Indoor Wall-Mount Antenna 50 Ohm (311234) is the high-efficiency inside antenna Wilson engineered for the WilsonPro Pro 710i industrial-grade cell signal amplifier and other WilsonPro boosters. It rebroadcasts the amplified signal inside the building across seven segments from 617 MHz to 2700 MHz. That range includes low-frequency 5G Band 71 and the worldwide LTE, CDMA, GSM, UMTS and AWS bands for voice and data. The antenna mounts flat on an interior wall and projects coverage into the space in front of it. Peak gain runs from 5.5 dBi at 617-698 MHz to 8.0 dBi at 1910-2170 MHz. Efficiency is above 75% and 70%, and front-to-back ratio reaches 18 dB in the upper bands, which helps keep indoor signal from leaking back toward the donor antenna. Electrical specs are 50 Ohm impedance, vertical polarization, an N-Female connector and 20 W of maximum power. The antenna measures 6.6 x 6.2 x 1.8 in and weighs 1.32 lb. It uses an aluminum radiator inside an ABS radome in a neutral color that suits offices, warehouses and retail floors. Installation is simple: the kit includes the antenna and a wall-mount bracket with hardware. The unit is assembled in the USA and covered by Wilson's 2-year warranty. A manufacturer spec sheet with radiation patterns is available for coverage planning in multi-antenna commercial deployments.
