Waveguide Low Power Elements
Series 680 cone elements provide an almost perfect impedance match over the full waveguide frequency range. Each unit employs an environmentally stable lossy material specially shaped to produce a low VSWR. For special applications, very short elements with a slightly higher VSWR are available. Also available are ceramic materials which can offer extremely high RF power capabilities. For more information on your specific application, contact factory.
