4G LTE 9dBi Indoor Dual Omni Antenna CRC9 3 m

The LTE-9IN-CRC9 is an indoor dual omnidirectional antenna for compatible equipment using 2G GSM, 3G UMTS, or 4G LTE connectivity. Its 850–2600 MHz operating range allows one antenna assembly to support the listed cellular technologies across a broad set of compatible frequency bands. With 9 dBi gain, the antenna is intended to improve the cellular connection available to the attached device, while the omnidirectional design allows it to work with signals arriving from different directions rather than requiring precise alignment toward a single source. The black housing and indoor operating designation make it suitable for placement inside homes, offices, technical rooms, or other protected locations where cellular equipment requires an external antenna connection.

The antenna uses two separate elements, each ending in a CRC9 Male connector, to provide the dual-connection arrangement required by compatible devices with two CRC9 antenna ports. This enables both antenna inputs to be connected through one matched product rather than through two unrelated antenna units. A VSWR below 1.5 indicates effective impedance matching within the specified frequency range, helping limit signal reflection in the antenna system. Compatibility should be checked before installation because both the connector format and the cellular bands supported by the connected device must correspond to the antenna. When these requirements are met, the LTE-9IN-CRC9 provides a straightforward dual-antenna solution for indoor cellular routers, modems, or other equipment fitted with matching ports.

A magnetic base provides a simple mounting method on suitable metal surfaces, allowing the antenna to be installed without drilling or permanent fixing. This is useful in indoor setups where the position may need to be adjusted during installation or changed later as equipment is moved. The base allows the antenna to be placed separately from the connected device, helping the installer choose a practical position within the available room layout. Because the product is specified for indoor use, it should be located in a protected environment rather than exposed to outdoor weather. The removable placement method also supports easier repositioning when access, furniture, cabinets, or nearby equipment affect where the antenna can be mounted.

Each antenna element is supplied with a 3 m RG174U cable, providing enough reach to route both connections from the magnetic mounting point to the device. The two equal cable runs preserve the dual-port arrangement and allow the antenna to be positioned away from the router, modem, or other compatible hardware when the device cannot be placed beside a suitable metal surface. One CRC9 Male connector is fitted to each cable, so both antenna ports can be connected individually through the same assembly. The combination of dual 3 m cables and magnetic mounting supports flexible indoor deployment while keeping installation uncomplicated. Product code LTE-9IN-CRC9 identifies this antenna for equipment with two compatible CRC9 antenna inputs.
