How to use

Attach the SMA male connector to the compatible SMA female port on your router, modem or radio device. Position the antenna vertically in a location that maximises line-of-sight to surrounding base stations or signal sources. For outdoor mounting, use appropriate fixtures and weatherproofing; ensure the connector and any cabling are protected from moisture.

Recommendations

The antenna is omni-directional, so placing it centrally and at an elevated position typically yields more uniform coverage. If reception is weak, try small adjustments in height and orientation or relocate the antenna closer to a window or an outdoor area with fewer obstructions.
