Precision Waveguide offers a series of pressure windows which are suited for use as low loss transitions from pressurized cabinets to unpressurized antennas and/or transmission lines. Pressure windows are constructed using Kapton dielectric material. These units are available in various configurations. The typical VSWR is less than 1.10 over the full frequency range and have an iridite finish.
