    Sierra Wireless 250u Antenna Adapter / Clear 4G+ Mobile USB Series S Antenna Adapter

    External antenna adapter for Sierra Wireless 250u, Clear 4G+ Mobile USB Series S and many other devices. Use this external antenna adapter to attach an external cellular antenna directly to your RF port. The adapter consists of a 18 to 20 inch cable with a connector crimped to each end. One end connects to the RF port on the back, side or top of your device. The other connector end attaches to your cellular antenna cable connector. This antenna adapter comes with an FME Male antenna connector to connect to any antenna or amplifier with an FME Female connector.

    Requires external cellular antenna not included.

    WARNING - To purchase this product, you must read this warning and agree to purchase and use this product at your own risk. Although it's rare, using this external antenna adapter can damage your device and void it's warranty. When an external antenna adapter is inserted into the port on your mobile device, your device's antenna is disconnected so that your device can receive signal through an external antenna. When you remove the adapter, your device's antenna should reconnect. If it does not, your device will show a weak or no signal and no service. This means that the switch that connects and reconnects the adapter is damaged or stuck. Despite the adapter manufacturer's testing, some devices may have weak ports and be damaged using this product. Damage may also be caused by pushing adapters in too far, twisting the connector when inserting or removing and by pulling on the adapter cable. As an alternative, we recommend a powered signal booster that does not require a connection through your devices RF port. These signal boosters will perform better than just an antenna directly connected to your device without the risk of plugging in an antenna adapter.
