In-Building Antennas: Designed specifically for use with building boosters, Wilson or now weBoost's full line of indoor antennas offers top performance and multiple mounting options. High-gain, wide-band directional Panel antennas are designed to mount on walls of homes, offices, buildings, and warehouses as they transmit signals effectively in one direction (ideal for long rectangular spaces or corridors). Panel antennas can be mounted on ceilings to project signal across multiple floors as well. For use in a building, we offer high gain, wide band Dome Antennas designed to distribute signal in all directions in 360 degrees fashion. Therefore, Dome antennas are suitable for square areas or for mounting at central locations. We have all interior antennas to best fit your wireless reception needs.
