Humidity
Jacketed waveguide assemblies are not affected by humidity, although condensation may penetrate non-sealed flanges.

Vibration
Waveguide assemblies have a low primary resonant frequency due to their low spring stiffness. Assemblies should therefore be supported at regular intervals to prevent large magnitude oscillations due to variable wind loading. In cold climates, consideration should also be given to potential ice loading and appropriate support provided.

Protective Jacket

Silicone: -70 to 170c
Our standard flexible waveguide is encapsulated using injection moulded silicone rubber to provide a high degree (IP68) of environmental protection.

Silicone is proven to be more resistant to ozone, UV, water and extremes of temperature than the inferior neoprene alternative offered by other waveguide manufacturers.

The unique design of the flange rear ensures that the moulded rubber jacket overlaps to create a secure, permanent environmental seal.

Polyolefin: -20 to 100c
For a limited number of applications and for longer lengths we can offer an adhesive lined polyolefin heat-shrink jacket. Due to the nature of the jacket, moulds are not required and lengths up to 5 metre are available depending upon waveguide size. These jackets are not recommended for use in the pressurised systems above 40kPa.
