TBMA8 30 MHz – 3000 MHz Hybrid Measurement Antenna

The TBMA8 is an affordable hybrid measurement antenna, a combination of a biconical antenna with a logarithmic periodic antenna, covering a frequency range of 30 MHz up to 3 GHz, targeting radiated emission EMC pre-compliance testing.

The TBMA8 is characterized from 30 MHz to 3000 MHz and has VSWR and antenna factor values typical for hybrid measurement antennas.

The TBMA8 is an average sized hybrid antenna, with its radiating elements and supporting booms made from aluminum alloy. It is equipped with a standard female N-connector and comes together with two triangular bowtie elements. The antenna provides a 20mm diameter mounting shaft (tube). An alternative, tiltable mounting element and tripods are available as optional accesories.

The TBMA8 is shipped in a robust carrying case.
