Product description
The TBMA3 is an affordable logarithmic periodic measurement antenna, targeting radiated noise EMC pre-compliance testing. The TBMA3 is characterized from 250 MHz to 1.3 GHz and has VSWR and antenna factor values typical for log-periodic measurement antennas. CISPR 16 divides the frequency range into several bands and defines specific antennas for each of these bands. For the frequency range above 300 MHz up to 1 GHz, CISPR 16 specifies using logarithmic periodic antennas (log-periodic antennas ) for radiated noise measurements.
The TBMA3 is an average sized log-periodic antenna, with its radiating elements and supporting booms made from powder coated 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 TBMDA3 is shipped in a robust carrying case, as pictured above.
