Sealed Dustproof Double Ridged Waveguide Feedthrough

WRD350 Double Ridged Wall Feedthrough Waveguide for Shielded Room Applications

This product is a professional Straight Waveguide featuring an integrated wall feedthrough design for passing signals through walls and shielded enclosures. The waveguide uses a WRD350 double ridged configuration and operates over a wide bandwidth. As a Wall Feedthrough Waveguide, it passes directly through walls, shielded enclosures, or equipment chassis without requiring additional holes or adapters. The integrated one piece construction combines mounting and feedthrough in a single step. The section length is 100mm, with custom lengths available upon request. The construction uses aluminum material with conductive oxidation and paint coating for durability. The interface is WRD350D24 flange for standard connection.

This wall feedthrough waveguide delivers excellent electrical performance across its operating band. The Voltage Standing Wave Ratio (VSWR) is rated at 1.2, which shows good impedance matching with low signal reflection. The insertion loss is very low, ensuring efficient signal transmission through the wall penetration. The double ridged design provides wide bandwidth coverage. The through wall section includes sealing treatment that prevents moisture and dust from entering equipment interiors. This extends the service life of the overall system. The robust aluminum construction provides good mechanical strength. The conductive oxidation and paint coating provide protection against corrosion and environmental exposure.

One clear strength of this Wall Feedthrough Waveguide is its ability to solve two core requirements simultaneously. It enables microwave signal transmission through walls while maintaining electromagnetic isolation between compartments. This creates clean cable routing with clear zone management. It is widely used in electromagnetic shield rooms and anechoic chambers where signals must pass between indoor sources and outdoor antennas. Other applications include radar equipment rooms connecting main radar units to antenna compartments, military shelters, vehicle mounted and airborne equipment, microwave base stations, satellite ground station facilities, industrial microwave systems, RF test laboratories, security millimeter wave scanners, and electronic warfare systems.

In practical use, this Wall Feedthrough Waveguide handles professional signal transmission through barriers very well. For electromagnetic shield rooms, it provides a reliable RF feedthrough that maintains shielding integrity. For radar systems, it connects transmitters in equipment rooms to antennas outside. For military shelters, it enables communication between inside and outside compartments while maintaining environmental sealing. The sealing treatment prevents moisture and dust ingress, making it suitable for outdoor and field deployments. The WRD350D24 flange mates securely with standard components. It stands as a solid example of a well designed wall feedthrough waveguide for reliable signal transmission through shielded enclosures and walls.
