The 3183B from ETS-Lindgren is an end-fed Mini-Biconical Antenna designed for chamber validation testing above 1 GHz. Operating from 1 to 18 GHz, this is an ideal receive antenna for performing the site VSWR chamber validation for the CISPR 16 standard. The radiation pattern is Omnidirectional in the H plane, allowing the antenna to receive signals from every direction around the axis. The antenna exhibits a VSWR better than 2:1 for most ranges, and never exceeds 5:1 above 1 GHz. The small size of the antenna enables it to be used for amplifier harmonic measurements when performing tests per IEC 61000-4-3. It is also ideal when performing the TDsVSWR test as per ANSI C63.25 standard. This antenna can handle an input power of up to 20 watts.
