3G/4G/LTE Omni-Directional Antenna – 3.5dBi Gain with SMA Male Connector & 3m Extended Cable

Product Description The 3G/4G/LTE Omni-Directional Antenna is a high-performance external signal booster designed to significantly improve data speeds and signal stability for cellular devices. With a powerful 35dBi gain rating, this antenna covers a wide frequency spectrum from 700MHz to 2700MHz, making it compatible with all major global carriers for 4G LTE, 3G, and GSM networks. It comes equipped with a 3-meter RG174 extended cable and a standard SMA Male connector, allowing for flexible placement in areas with better reception, such as near windows or outside vehicle cabins. The omni-directional radiation pattern ensures consistent signal capture from all directions without the need for precise alignment, making it perfect for IoT gateways, industrial routers, and mobile hotspots.

Key Features

• High 35dBi Signal Gain: Significantly boosts weak signals in remote areas, enhancing download speeds and reducing latency for 4G/LTE devices.

• Wideband Compatibility: Supports a broad frequency range (700-2700MHz) covering LTE, 3G, HSPA+, and GSM bands.

• Omni-Directional Pattern: Receives and transmits signals from 360 degrees, eliminating the hassle of pointing the antenna toward a specific cell tower.

• Extended 3-Meter Cable: The long-reach RG174 cable allows for optimal positioning of the antenna away from interference-heavy electronics.

• Versatile Mounting: Features a magnetic suction base for quick and secure attachment to metallic surfaces like vehicle roofs or outdoor enclosures.

Technical Details
