VHF Collinear Antennas
Professional VHF collinear antennas designed for omnidirectional gain applications where communication is required with multiple outstations in varying locations. Available in 3dB and 6dB models, with tapered gloss white or parallel matt black radome options to suit different path requirements and installation environments.
The internal radiating element is DC grounded and housed within a high dielectric fibreglass radome to help minimise precipitation and wind static for low-noise operation. Built using quality materials for long service life, these antennas feature stainless steel radials and are recommended for use with the heavy duty Universal Clamp for mounting to vertical or horizontal supports.
Models PRO-COL3V, PRO-COL6V & PRO-COL3V-RG, PRO-COL6V-RG
The VHF collinear design is an omnidirectional gain antenna and can be used where communication with a number of randomly placed outstations is required. They are available in 4 models to suit path requirements and installation environment.
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 COL3V & COL6V models radome is tapered and finished in gloss white.
The COL3V-RG & COL6V-RG models radome is parallel and finished in matt black.
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 Clamp is recommended and enables mounting to either a vertical or horizontal mounting support.
