How to use

Connect the antenna to a compatible device using the SMA connector. Position the antenna vertically for omni-directional coverage and avoid obstructions near the radiator to maintain signal performance. The compact form factor allows mounting on flat surfaces or integration into equipment enclosures as required by your installation.

Recommendations

For best results, place the antenna clear of large metal objects and away from other antennas to reduce interference. If used outdoors or in exposed locations, ensure the SMA connection and device interfaces are protected from moisture. Verify device and network band compatibility within the 0.7–4 GHz range before installation.
