TBMA12 30 MHz – 6000 MHz Hybrid Measurement Antenna

The TBMA12 is an affordable hybrid measurement antenna for radiated emission measurements. The antenna is a combination of a biconical antenna with a logarithmic periodic antenna, covering the frequency range from 30 MHz to 6 GHz. The TBMA12 is characterized from 30 MHz to 6000 MHz and has VSWR and antenna factor values typical for hybrid measurement antennas. The TBMA12 is an average sized hybrid antenna, with its radiating elements and supporting booms made from aluminium. It is equipped with a standard female N-connector and comes together with two triangular bowtie elements. The antenna provides a 22mm diameter mounting shaft. A suitable fiberglass tripod, model TBTP5 and mounting adapter TBMA8-PAT are available as optional accessories. The TBMA12 is shipped in a robust carrying case.
