The TBMA7 is an affordable logarithmic-periodic measurement antenna, targeting radiated noise EMC precompliance testing.

The TBMA7 is characterized from 150 MHz to 3000 MHz and has VSWR and antenna factor values typical for logarithmic-periodic measurement antennas.

The TBMA7 is an average sized logarithmic-periodic 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 an antenna bracket and a mounting adapter. A standard ¼” thread on the bottom of the mounting adapter makes it easy to connect it to most standard tripods.

The TBMA7 is shipped in a robust carrying case, as pictured above.
