Active, handheld shielded Loop Antenna with nearly constant antenna factor over the entire frequency range (9 kHz – 30 MHz). The active loop antenna is especially suitable for mobile applications, e.g. with a handheld spectrum analyzer. Combined with a CISPR 16 EMI-receiver a convenient field-strength measuring system with low noise and pulse measuring capabilities is composed. The robust, milled aluminum housing comes with two 3/8" large camera threads to accept a handle or to be mounted on a tripod (e.g. AM 9144). The FMZB 1513 is equipped with 10 NiMH-Mignon cells to keep the weight as low as possible for mobile use. The battery voltage is indicated with a green LED for normal operation, with both red and green for reserve and with red only for urgent recharge requirements. Although it is possible to measure during recharging, we do not recommend to do so because of most NiMH chargers operate in pulsed mode and create an unwanted disturbance.

Applications:

The Active Loop Antenna FMZB 1513 can be used for the frequency selective measurement of magnetic fields (of fictitious electric field) in the longwave, midwave, and shortwave frequency ranges. It can be used for testing according to CISPR (e.g. 16-1-4), MIL, FCC, EN, ISO, ANSI, ETSI, and many other standards. 

Pedestal Stand  

The optional pedestal stand (1513 STAND) eases the assembly and storage of the antenna on straight surfaces.
