Flexible twist waveguide
Flexible waveguide is a necessary component of the feeder in microwave communication system. It has excellent flexible performance, and it can remain good electrical performance when in bending and torsion.
Flexible waveguide assembly is mainly composed of the inner conductor, flange and jacket. The inner conductor is rectangular twistable corrugated pipe, it also can be torsion when in bending, So the flexible twist waveguide can meet the needs of the antenna with different direction. We can design the flange upon customer request, to meet the needs of the different customers. Black silicone or neoprene rubber jacket can provide protection, ensuring flexible waveguide can work well under various environments.
The flexible twist waveguide Huacheng produced carries a wide range of types. Frequency 1.13-50.1Ghz.
