3G/4G LTE 5 dBi Indoor Omni Antenna with SMA Connector

The JCG024 is an external GSM antenna designed for cellular communication across the 824–960 MHz and 1710–2170 MHz frequency ranges. Its linear polarization and 5.0 dBi zenith gain support signal transmission and reception within the specified bands, while the 50-ohm impedance provides compatibility with matching radio equipment. A VSWR below 2.0 indicates that the antenna is designed to transfer radio-frequency energy efficiently across its operating range. The tall whip-style element and integrated loading coil form a compact external assembly suitable for installations where the antenna must be positioned away from the connected device.

The antenna uses a magnetic base, allowing it to be placed on an appropriate metal surface without permanent drilling or screw mounting. This installation method makes repositioning straightforward when the antenna location needs to be adjusted. An RG58 cable links the antenna to the equipment, and SMA or other connector options allow the termination to be selected for the intended interface. The antenna measures approximately 311 mm in overall height, while its 40 mm base keeps the mounting footprint compact. It is specified for operation from -40 °C to +85 °C and is tested for vibration from 10 to 55 Hz with 1.5 mm amplitude over two hours. RoHS compliance confirms conformity with the stated environmental requirement.
