The Wilson W601-0027 Cellular Signal Booster, 300mm, NF 698-4200MHz is a cellular signal booster built for the space it's installed in, part of the weBoost/WilsonPro line of bidirectional amplifiers that pick up an existing outside carrier signal and rebroadcast it indoors or in-cabin. It works across all major U.S. carrier networks (Verizon, AT&T, T-Mobile, and others) without requiring a specific carrier plan, and is designed for straightforward self-installation with the antenna, cabling, and amplifier unit included.
