Description & Specification
WR137 Waveguide to Coaxial Adapter (Model: WC-137-PDR-NF)
5.85 - 8.2 GHz | The SatCom Workhorse | Core Interface for HS-137 Series
The WC-137-PDR-NF is engineered as the backbone of C-Band connectivity. Operating seamlessly from 5.85 to 8.2 GHz, this adapter is the dedicated coaxial interface for the HS-137 Standard Gain Horn Antenna series. It represents the "SatCom Standard," providing a reliable, low-loss transition between waveguide components and coaxial systems. With a VSWR of 1.25 and a compact 145g form factor, it ensures signal purity for satellite uplinks, weather radar, and maritime communications while maintaining the ruggedness required for field deployment.
