SW20284EB56 SWE037 4G/LTE & NB-IoT External Terminal Antenna (SMA Connector)

Product Overview: The SW20284EB56 (SWE037) is a compact, wideband external terminal antenna designed for global cellular deployments across 2G, 3G, 4G LTE, and NB-IoT network bands. Engineered specifically for small-size IoT terminals and space-constrained equipment, this passive whip antenna provides reliable network coverage. It features an integrated tilt-and-swivel hinge and a standard threaded SMA connector, enabling a clean plug-and-play installation directly onto cellular routers, wireless modules, and smart devices.

Key Features:

• Wideband Cellular Support: Fully optimized for 2G, 3G, 4G LTE, and NB-IoT devices operating in low and high frequency spectrums.

• Ultra-Compact Profile: Engineered with a small footprint, making it the perfect solution for miniature industrial IoT terminals and portable enclosures.

• Threaded SMA Connection: Screws directly onto the device's RF bulkhead interface, eliminating the need for internal layout adjustments or external cabling.

• Adjustable Knuckle Swivel Joint: The mechanical hinge allows the antenna body to bend up to 90 degrees and swivel freely to orient the element for optimal signal path alignment.

• Industrial Build Durability: Housed in robust ABS material to ensure steady electrical performance across industrial operating temperature fields.

Frequently Asked Questions: Q1: Is this antenna suitable for Narrowband IoT (NB-IoT) hardware? A1: Yes. The SWE037 is explicitly engineered for NB-IoT protocols and equipment, providing the necessary low-band wideband coverage required for low-power, wide-area industrial communications.

Q2: Can I mount this antenna straight onto a router placed in a cabinet? A2: Yes, it connects directly via its threaded SMA interface. However, for maximum signal strength and efficiency, make sure the adjustable whip element can be positioned in an open direction away from heavy metallic shielding blockages.
