Product Description The 3.5dBi 4G LTE Omni Antenna is a high-performance signal booster designed to stabilize and enhance cellular connectivity for IoT gateways, industrial routers, and remote monitoring systems. This antenna covers a broad frequency spectrum from 700MHz to 2700MHz, ensuring compatibility with almost all global 3G and 4G LTE carriers. Its omni-directional pattern allows it to receive signals from all directions, eliminating the need for precise alignment with a cell tower. Equipped with a 3-meter cable and a strong magnetic base, it can be easily mounted on metallic surfaces or positioned near windows to bypass signal-blocking walls.
Key Highlights
Universal 4G/LTE Support: Optimized for the wide range of bands used by Indian telecom providers (Airtel, Jio, Vi), ensuring faster data speeds and lower latency.
Extended Reach: The included 3-meter RG174 cable allows you to place the antenna in a high-reception area while keeping your router or modem safely inside an enclosure or cabinet.
Easy Installation: Features a magnetic base for instant mounting on metallic cabinets, vehicle roofs, or window frames without the need for drilling or specialized hardware.
SMA Male Connector: Uses the industry-standard SMA Male connector, making it directly compatible with most 4G routers (like TP-Link, Huawei, D-Link) and GSM modules (like SIM800, SIM7600).
Weather-Resistant Build: The robust radome is designed to withstand typical indoor and sheltered outdoor environments, providing long-term reliability for remote installations.

Installation Tip from Robogears To get the best performance, place the antenna as high as possible and away from other high-frequency electronics that might cause interference. If you are using this with a dual-antenna router (MIMO), it is best to use two of these antennas spaced at least 20cm apart to maximize data throughput. Ensure the SMA Male connector is tightened firmly but not over-tightened; a finger-tight connection is usually sufficient to maintain signal integrity.
Note: This product is an external antenna. Cellular reception depends on local network availability and tower distance. Product images are for illustration purposes only.
