The WBHA 0104-1 from Milmega is a Horn Antenna that operates from 1 to 4 GHz. It features optimizing lens for automotive radar pulse testing at a 1-meter test distance as required by GMW 3097 and EMC-CS-2009. This antenna delivers a gain of over 13 dBi and can handle a peak power of 6000 watts. The device has a VSWR (no lens) of less than 1.6:1 and a 3dB beamwidth of up to 39 degrees. The lens improves the gain of the antenna when used at 1-meter which means that the required 600 V/m field strength can be achieved with around 800 watts in the 1.2-1.4 GHz range and with as little as 400 watts in the 2.7-3.1 GHz frequency range. This antenna measures 550 x 540 x 897 mm and is available with a 7/16 connector.
