Pressure Windows
Microtech's Pressure Windows are engineered, designed, and manufactured "in house".
Microtech's Pressure Windows are used where it is desirable to environmentally isolate a section of transmission line or component, to increase power-handling capacity, or to prevent corrosion in high ambient humidity or dusty conditions.
