4G LTE 3dBi Indoor Omnidirectional Antenna with SMA Male Connector

The JCW440 is a compact omnidirectional LTE antenna designed to improve wireless connectivity for compatible cellular devices operating across a wide range of mobile network frequencies. It supports both the 698–960 MHz and 1710–2690 MHz bands with 3 dBi gain, making it suitable for equipment that communicates on low- and high-frequency LTE networks. Its omnidirectional design allows the antenna to receive and transmit signals from multiple directions, eliminating the need for precise alignment with a cellular base station. This makes installation quick and convenient, especially when the device may be repositioned or used in different indoor locations. The antenna connects through a standard SMA Male RF connector, providing compatibility with equipment that uses the corresponding antenna interface.

Designed for indoor use, the JCW440 offers a practical upgrade or replacement antenna for LTE routers, gateways, modems, and other devices equipped with an SMA antenna connector. The compact black housing occupies little space and integrates easily with desktop or wall-mounted equipment without affecting everyday operation. The moderate 3 dBi gain provides a balanced combination of signal coverage and installation flexibility, making the antenna suitable for general-purpose indoor deployments where a simple omnidirectional solution is preferred. By supporting multiple cellular frequency ranges in a single antenna, it eliminates the need for separate antennas for different LTE bands and simplifies deployment of compatible networking equipment.
