MOBILE SMA ANTENNA.

It is primarily used to provide or enhance cellular reception (2G, 3G, and 4G/LTE) for Teltonika’s industrial networking hardware.

1. Compatible Devices

This antenna is a standard accessory for almost all of Teltonika’s mobile routers and gateways that have an SMA Female connector. It is commonly used with:

• RUT Series: RUT200, RUT240, RUT241, RUT360, RUT950, RUT955, RUT956.

• RUTX Series: RUTX09, RUTX11, RUTX12, RUTX14, RUTXR1.

• TRB Gateways: TRB140, TRB141, TRB142, TRB145, TRB245, TRB255.

• TRM Modems: TRM240, TRM250.

2. Typical Usage Scenarios

The PR1US440 is used in environments where a stable mobile connection is critical:

• Inside Industrial Cabinets: If a router is placed inside a metal electrical cabinet (which blocks signals), this antenna is often connected via an extension cable to the outside of the box to catch the signal.

• Remote Locations: It is used in rural or industrial sites (like wind farms or water treatment plants) to boost the 4G/LTE signal in areas where reception is weak.

• Fleet & Transport: It is often the default antenna used for routers installed in buses, trucks, or trains to provide Wi-Fi to passengers or track GPS data.

• Backup Internet: In offices, it is used on a router (like the RUTX11) as a "failover" antenna—so if the main fiber internet goes down, the antenna ensures the LTE backup has a strong enough signal to take over.

3. Key Technical Specs

• Connector: SMA Male (the screw-on type with a pin in the middle).

• Frequency Range: 698–960 MHz / 1710–2690 MHz (covers all global 4G LTE bands).

• Gain: 3.0 – 4.0 dBi (this provides a moderate boost over standard internal antennas).

• Design: It usually features a swivel/hinge design, allowing you to angle it 90 degrees to clear space or align it with the nearest cell tower.
