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.
