Description Tekbox TBMA5 Active Monopole Antenna 9kHz – 30MHz The TBMA5 is an active Monopole Antenna, expanding the Tekbox product range of affordable EMC pre-compliance test equipment. The monopole antenna is designed for radiated emission measurements within the frequency range 9 kHz – 30 MHz, according to CISPR 16. The monopole antenna has a rod with a height of 104 cm and provides sufficient sensitivity to carry out radiated emission measurements as specified in CISPR 25 or MIL-STD-461G. The TBMA5 consists of an impedance converter, a universal charger, a 10 mm diameter rod, a 60 cm x 60 cm ground plane and a standard 10pF calibration adapter. Furthermore, it includes the coaxial cable with ferrite and grounding equipment required under MIL-STD-461G. The impedance converter is equipped with a ¼” thread to attach it to conventional tripods.
