ETS-Lindgren's 3106B Double-Ridged Guide Antenna is especially effective for generating high electromagnetic fields with relatively low power input. 

The antenna is also useful for receiving low-level signals where high gain characteristics are needed. Although large in size, 93.3 cm (36.7 in), this antenna weighs only 11.8 kg (26 lb). A Type N female connector is used for increased power handling and optional RF connectors are available. 

The 3106B Double-Ridged Guide Antenna has uniform gain through its frequency span, providing efficient performance characteristics and directionality. It can handle 1000 W peak and 800 W continuously. Constructed of lightweight corrosion-resistant aluminum, our 3106B Double-Ridged Guide Antenna will provide years of trouble-free indoor and outdoor service.​​
