The FMZB 1519 C is an active, shielded loop antenna engineered for precision EMC field-strength measurements from 9 kHz to 30 MHz. Battery operation eliminates mains-borne noise, while the robust milled-aluminum enclosure and integrated overload indicator ensure reliable performance under the most demanding test conditions .
Wideband Response (9 kHz – 30 MHz) with ±1 dB antenna factor stability
Dual Antenna Factors
E-field (fictitious): 20 dB/m
H-field: –31.5 dB Ω·m
Low-Noise, Pulse-Capable when used with a CISPR 16-1-1/16-1-4 receiver
Battery-Powered (10 × NiMH cells) for >12 h operation (typ. 20 h)
Overload Indicator LED alerts at 1 dB compression threshold
Versatile Mounting: 3/8″ & 1/4″ tripod threads plus top camera threads for handles or stands
Rugged Construction: Milled-aluminum, IP-rated housing for field or chamber use
Frequency-selective measurement of magnetic or “fictitious” electric fields in longwave, mediumwave, and shortwave bands
Compliance testing per CISPR 16-1-4, MIL-STD, FCC, EN, ISO, ANSI, ETSI, and other global standards
Pre-compliance and full-compliance EMC test labs requiring low-noise, repeatable field-strength data
