The COL5810 5.8 GHz ISM U-NII-3 band antenna offers an omnidirectional pattern enabling optimum network configuration with a high 10 dBi gain. The patented PCB-based design delivers consistent VSWR, pattern and tilt characteristics across the entire operating bandwidth, by removing manufacturing variations found in other, more traditional mechanical collinear designs.

It is covered with black fibreglass radome, matching black cap and delrin connector housing, making it ideal for outdoor applications. Mounted by a durable M13 nickel plated stud. Also available in a medium gain 6 dBi version.
