18DBi High Gain Outdoor Magnetic Antenna, 4G 3G GSM LTE 700-2700MHz (36cm)

[Signal Boost] The outdoor antenna significantly amplifies weak cellular signals. Enjoy stronger reception, faster data speeds, and more reliable 4G, 3G, GSM, and LTE connections in fringe coverage areas. [Wide Band Coverage] Supports all major cellular bands from 700–2700 MHz, ensuring compatibility with global 4G/LTE frequencies, 3G, and GSM networks. No need for multiple antennas — a single unit handles voice and data across carriers. [Triple Base] Equipped with three strong suction cups and a magnetic base, this 36cm antenna attaches firmly to metal roofs, RVs, vehicles, or outdoor cabinets. The three‑point fixation prevents movement in wind or vibration, maintaining optimal signal direction. [Extra‑Long Cable] The 3m long cable allows you to place the antenna at the best signal location — such as a roof, balcony, or window — while keeping your router or signal booster indoors. This separation minimizes interference and maximizes gain performance. [Outdoor Construction] Built to withstand sun, rain, snow, and extreme temperatures, this 36cm pole antenna features a UV‑stabilized housing and sealed connections. The rugged design ensures years of reliable service in harsh outdoor environments without signal degradation.
