Benefits of the TekBox TBMA Series Antennas for EMC Measurements
- Biconical antennas: EMC radiated emission testing and generating defined field strength.
- Test standards: FCC, CISPR, SAE, RTCA-DO-160, Mil STD-461, etc.
- Horn antennas: For radiated noise measurements, frequency range 1...8 GHz.
TekBox TBMA Bionical, Log-periodic, Monopole, Loop, and Double Ridged Horn Antennas
Models TBMA1, TBMA2, TBMA3, TBMA4, TBMA5B, TBMA6-P, TBMA7, TBMA8
The TekBox TBMA series are biconical, logarithmic periodic, active monopole antennas, passive loop antennas, and double ridged horn antennas for EMC measurement. They are used for testing and generating EMC radiation emissions.
