The internal radiating element is DC grounded and is housed in a high dielectric fibreglass radome to minimise the effects of precipitation and wind static. This provides for low noise operation. The radome is tapered and finished in gloss white. Stainless steel radials are fitted to the hub above the mounting section.
Construction of the antenna utilises quality materials to ensure long life and reliable operation. The heavy duty Universal Mounting Clamp (CLUV) is provided with the Collinear and enables mounting to either a vertical or horizontal mounting support.
