This premium **Multi-Band GSM & RF Magnetic Mount Antenna** is a highly versatile, commercial-grade communication solution designed to deliver exceptional signal reinforcement across various cellular and remote control radio bands. Engineered specifically to eliminate dead zones and improve signal stability, this omnidirectional external whip is fully compatible with GSM 900 MHz, DCS 1800 MHz, and UMTS/3G 2100 MHz bands. Additionally, it offers outstanding support for license-free 868 MHz and 869 MHz industrial, scientific, and medical (ISM) bands commonly used in automated remote control systems, telemetry, smart metering, and IoT sensor arrays.
This high-efficiency antenna features a robust, removable magnetic base with a compact 2.8 cm footprint, allowing for stable, non-invasive mounting on any flat ferrous metal surface—such as vehicle roofs, metallic enclosures, or outdoor cabinets. The base is pre-wired with an extended 5-meter low-loss coaxial cable terminating in a versatile FME and SMA male connection assembly, providing plenty of slack for clean, professional cable routing. Physically measuring 20 cm in length, the radiator has been optimized to provide a powerful signal gain of up to 6 dBi in the lower 868, 869, and 900 MHz bands, and a highly reliable 4 dBi of gain in the higher 1800 and 2100 MHz frequencies.
Built to meet demanding industrial standards, this external antenna serves as a perfect direct replacement or signal booster for critical cellular telephone couplers, lift/elevator emergency intercom systems, and security switchboards. It is fully compatible as a replacement whip for popular cellular terminal gateways, including the GSM FCT-400 and CELL50 fixed wireless links (FCTs). Whether deployed for elevator security lines, remote machinery monitoring, gate automation, or telecommunication backup systems, this rugged antenna guarantees steady, uninterrupted data and voice signal transmission.
