Biconical Antenna

EM-6912A | 30 Mhz – 300 MHz

A balun, feedline, and element cage give the Electro-Metrics EM-6912A response curves that are almost linear, making it ideal for swept measurements. An added benefit is that the EM-6912A has an improved BALUN design, which makes it insensitive to changes of orientation while vertically polarized. Readings obtained will be the same no matter which element is closest to the ground plane, eliminating a potential source of measurement error.


The EM-6912A Biconical Antenna operates over the 30-300 MHz frequency range. The antenna is ideally suited for use in FCC, SAE, and MIL- STD radiated emissions testing. The EM-6912A broadband frequency capability eliminates the need for band switching, element extension, or external tuning when used for electromagnetic ambient surveys or spectrum signature measurements. The compact size of the EM- 6912A is advantageous for use in anechoic chambers and shielded enclosures.
