Verkko-SMA-antenni Teltonika PR1US740, SMA-liitin, 4 dBi, 0,450–2,180 GHz

Teltonika PR1US740 is a compact external SMA antenna designed for network equipment with a male SMA connector. It provides up to 4 dBi gain across multiple cellular and wireless bands, covering 0.450–0.466 GHz, 0.716–0.960 GHz and 1.710–2.180 GHz. With 50 Ω impedance and a lightweight construction, this antenna is suitable for improving reception and signal stability on routers, gateways and IoT devices. The product is certified to meet REACH and RoHS requirements.

Advantages

The antenna offers multi-band coverage in a single, compact form factor, enabling support for a range of cellular and narrowband frequencies without the need for multiple antennas. Its 4 dBi nominal gain contributes to improved uplink and downlink performance in many deployment scenarios while maintaining a low profile and minimal weight. The SMA male connector ensures compatibility with a wide range of consumer and industrial network devices.

How to use

Attach the Teltonika PR1US740 to the SMA female connector on your router, gateway or other network device by carefully screwing the SMA male connector until it is hand-tight; avoid overtightening. Position the antenna vertically for general coverage or adjust orientation based on signal strength measurements for optimal reception. Ensure the host device is powered down or follow manufacturer guidelines when connecting or disconnecting external antennas to avoid damage.

Recommendations

For best results, place the antenna where it has a clear line of sight to the nearest base station and away from large metal objects or sources of interference. If signal conditions are poor, test different mounting positions and orientations. Use proper weatherproofing or an appropriate enclosure when installing the antenna in outdoor or exposed environments.
