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 aluminum, making it durable and relatively lightweight. To maximize performance, a type N connector is used (other connectors available upon request).

  • 100 MHz to 1 GHz Frequency Range
