About The Wilson Building Mount Cellular Antenna

The Wilson Omni-Directional Building Mount Cellular Antenna is made for building cellular amplifier / repeater systems, DirectConnect type amplifiers or a direct connection to a cell phone or other mobile cellular device such as a data card, Hotspot or MiFi device. The antenna is weatherproof and fiberglass-encased and is omnidirectional. It is ideal for building signal booster installs for homes, office buildings, portable buildings, trailers, etc. The antenna has a built-in radial ground plane for maximum performance.
