Precision Waveguide offers a series of bulkhead feed-thrus for extending waveguide through a pressurized wall or cabinet. A heavy mounting flange and gasket provide sealing. The typical VSWR is less than 1.10 over the full frequency range.
Bulkheads are furnished with standard choke to cover flanges and an iridite finish. Custom bulkheads are also available.SPECIFICATIONS
