The Tekbox TBMA3 is a log periodic measurement antenna designed for EMC pre-compliance testing and radiated emission analysis in the frequency range from 250 MHz to 1.3 GHz. The antenna is developed for EMC measurements according to CISPR 16 and provides VSWR and antenna factor characteristics typical for log periodic EMC antennas.
TBMA3 features radiating elements and support booms manufactured from powder-coated aluminum alloy and is supplied with an N-type female connector, mounting bracket, and mounting adapter. A standard 1/4" thread allows easy installation on common tripods. The antenna is delivered in a rugged aluminum carrying case for transport and storage.
The antenna provides a nominal impedance of 50 Ω, supports up to 100 W continuous RF input power, and offers isotropic gain of approximately 6 dBi. The characterized antenna factor ranges from 14.2 to 27.5 dB/m across the specified frequency range.
TBMA3 is intended for radiated noise measurements and EMC emission testing together with spectrum analyzers and EMC test equipment. The antenna is suitable for laboratory, development, and verification environments requiring repeatable EMC pre-compliance measurements
