3112 Double-Ridged Guide Antenna
Frequency Range: 100 MHz – 1 GHz
ETS-Lindgren’s Model 3112 Double-Ridged Waveguide Horn is a linearly polarized broadband antenna providing high gain and excellent VSWR characteristics over a broadband frequency range of 100 MHz to 1 GHz. The antenna is especially effective for generating high electromagnetic fields with relatively low power input.
The 3112’s high gain makes it suitable for generating the high fields (200 V/m) necessary per the ISO 11451-2 and SAE J551/11 full-vehicle automotive radiated immunity standards with less than 2 kW. Additionally, since the model 3112 is a double-ridge waveguide horn, it is the accepted antenna for MIL-STD-461E, bringing the desirable performance of this type of antenna lower frequencies.
Like other double-ridged waveguides in this series, the Model 3112 is precision manufactured from aluminium, making it durable and relatively lightweight. To maximize performance, an EIA 1 5/8” flange connector is used (other connectors available upon request). Each antenna is individually calibrated at our A2LA accredited test lab and comes with actual factors and a signed Certificate of Conformance. A two-year warranty is included.
