Collinear omnidirectional antennas in a UV-stable fiberglass radome for 360 degree outdoor coverage. This page covers how the class behaves specifically in antenna polarization explained work, and lists the 11 catalog models that fit.
What this class does well
A collinear omni covers every azimuth from a single feed, so one antenna serves subscribers in any direction and no re-aiming is ever needed. The sealed fiberglass radome handles years of UV and weather without maintenance.
Where it falls down
Gain only comes from flattening the elevation pattern. A high-gain collinear on a tall mast will underserve everything close to the base, and the tall radome is a significant wind load.
The range we stock
Across the 11 models in this class the gain runs from 6 to 15 dBi, frequency coverage from 428 to 5850 MHz, and the longest dimension from 480 mm to 1550 mm. Check the size figure early. It decides the mount, and on a shared mast it decides whether the part fits at all.

Specifying one for antenna polarization explained
Vertical polarization is standard for omnidirectional mobile and broadcast use; horizontal and circular polarizations are chosen to reduce interference or to handle reflective and orientation-varying paths. Confirm the connector before ordering: changing the interface later means either an adapter, which adds a mismatch and a failure point, or a re-terminated cable. Standard builds ship with an N-Female interface.
