4G LTE 9dBi Indoor Dual Omni Antenna, SMA Male, 3m

The LTE-9IN-SMAM is an indoor dual omni-directional antenna designed for compatible 3G UMTS and 4G LTE equipment. Its two separate antenna elements provide a dual-connection arrangement for routers, modems, and gateways that use two external cellular antenna ports. Because both elements are omni-directional, the antenna does not need to be aimed toward a specific base station. This makes it suitable for indoor locations where the direction of the available cellular signal may not be known in advance or where convenient placement is more important than directional alignment. The two-element design also keeps both cellular connections within one coordinated antenna setup, simplifying placement around the connected equipment.

Operating across the 850-2600 MHz range, the antenna covers the cellular frequencies stated for the product and can be used only when those frequencies match the bands supported by the connected device. Each element provides 9 dBi gain, helping the antenna collect and deliver cellular signals to compatible equipment within its specified range. The dual-element format allows both antenna inputs of a suitable device to be connected rather than leaving one port unused. Before installation, the device frequency bands should be checked against the antenna range so that the selected router, modem, or gateway can use the antenna as intended. This compatibility check is especially important because the antenna is defined for a specific frequency range rather than for every possible cellular band.

Each antenna element is supplied with its own 3 m cable and SMA Male connector, allowing both elements to reach the corresponding ports on compatible cellular equipment. The cable length gives flexibility when placing the antenna away from the device, such as on a nearby metal surface where positioning may be more practical. Two SMA Male connectors are provided, so compatibility depends on the connected equipment having two matching SMA antenna ports. Checking the connector type before installation avoids the need for unsupported connections and helps ensure that both antenna elements can be used as designed. The separate cables also allow the two antenna elements to be positioned independently while remaining connected to the same device.

A magnetic base supports quick placement on a suitable metal surface without requiring a permanent mounting arrangement. This makes the antenna easy to reposition during setup while remaining intended specifically for indoor use. Its black finish provides a neutral appearance for placement near networking equipment, office furniture, cabinets, or other suitable indoor surfaces. The product can be identified by the LTE-9IN-SMAM code and EAN 0708747433630, which helps distinguish this SMA-equipped version during ordering and stock handling. Placement should be selected with both the 3 m cable reach and access to the device's two antenna ports in mind. A suitable metal surface is required for the magnetic mounting method to function as intended.
