Tekbox TBLLA-2M 9kHz...30MHz Large Loop Antenna (LLA)
Tekbox TBLLA-2M 9 kHz...30 MHz Large Loop Antenna
The Tekbox TBLLA-2M is a large loop antenna (LLA) with three orthogonal loops, as required by CISPR 16 -1-4 and CISPR 15/EN 55015. The TBLLA-2M is used to measure the current induced by the magnetic field emitted by luminaries. It consists of three perpendicular 2 m diameter loop antennas on three orthogonal planes (X/Y/Z), set on lightweight hollow WPC frames with a total height of 2.5 m. The loops lowest point is 0.5 m above ground. Each loop element receives magnetic field radiation normal to the containing plane and generates a voltage signal proportionate to the strength of the H-field radiation at the output port of the RF transducer connected to the loop.
- LLA/large loop antenna (triple loop).
- Frequency range 9 kHz...30 MHz.
- Standards CISPR 16-1-4, CISPR 15.
- 3 perpendicular loops with 2 m diameter.
- Loop construction: RG223U sections with over-molded slits inside PEX tube.
- RF transducer transfer impedance typ. 0 dBΩ; 1 V/A at 9 kHz...30 MHz.
RF transducer output connector N-female, 50 Ω - Antenna validation factor within ±2 dB compared to the theoretical validation factor for 2 m diameter LLA given in CISPR 16-1-4.
- Effective antenna correction factor 0 dB.
- CM resistance of the ferrite absorbers >200 Ω at 10 MHz.
- Mechanical dimensions (LxWxH, mm): 2062 x 2062 x 2547; 25 kg.
The Tekbox TBLLA-2M is equipped with three TekBox TBCCP1-2K70 coaxial RF current monitoring probes (transducers), with a flat transfer impedance of 0 dBΩ (1 V/A) from 9 kHz...30 MHz when loaded with 50 Ω. The kit comprises all required coaxial cables, ferrite clamps, a manual RF coaxial switch to select loops, and a TBTP3 tripod with a plastic DUT support plate.
A calibration dipole with support structure is available as optional accessory.
