The UHF Collinear design is an omnidirectional gain antenna and can be used where communication with a number of randomly placed outstations is required. It is available in three models and two finishes to suit path and durability requirements.
The internal radiating element is housed in a high dielectric fibreglass radome to minimise the effects of precipitation or wind static to provide low noise operation.
A 1m RG213 tail is fitted as standard.



COLVU3, COLU6 & COLU8
These models the radome is tapered and finished in gloss white.
The antenna is constructed with high quality materials to ensure long life and reliable operation. The heavy duty Universal Mounting Clamp (CLUV) is provided, which enables mounting to either a vertical or horizontal mounting support.

COLVU3-R, COLU6-R, COLU8-R
These models are parallel and finished in matt black.
The antenna is constructed with high quality materials to ensure long life and reliable operation. The heavy duty Universal Mounting Clamp (CLUV) is provided, which enables mounting to either a vertical or horizontal mounting support.
This model is more durable in high wind speed environments.
