3119 Double-Ridged Waveguide Horn
Frequency Range: 400 MHz – 6 GHz
The Model 3119 Double-Ridged Waveguide horn is a the latest addition to a family of double ridge waveguides for wireless and EMC measurement from ETS-Lindgren. Users of this antenna benefit from uniform illumination of target surfaces and accurate gain measurement. In addition, the Model 3119 exhibits high gain and low VSWR across its operational frequency band, accepting power input of 1500 watts.
The Model 3119 sweeps from 400 MHz to 6 GHz without stopping for band breaks, making it ideal for automated testing, it also covers all the commercial wireless frequencies.
This antenna uses a Type N connector, and accepts up to 1500 watts of continuing input power with up to 2500 watts of peak power. The antenna’s high gain and low VSWR over its operating frequency translates into efficient amplifier use and high field strengths.
