The Model 3180D Broadband Mini-Bicon Antenna is designed for optimal performance across the frequency range of 30 MHz to 1 GHz (cage elements) and 30 MHz to 3 GHz (cone elements). The uniquely designed elements provide an omnidirectional pattern and are ideal for free space NSA (FSNSA) tests for fully anechoic rooms. It's small size also allows for harmonic monitoring when testing per the IEC 61000-4-3. The 3180D covers the traditional frequency range for EMC measurements and covers all of the VHF and UHF bands, making it ideal for spectrum monitoring of FM, TV, and some cellular phones.
