TBMA3 LOG PERIODIC MEASUREMENT ANTENNA<\/h1>\n
\n

The TBMA3 is an affordable logarithmic periodic measurement antenna, targeting radiated noise EMC pre- compliance testing.<\/p>\n

The TBMA3 is characterized from 250 MHz to 1.3 GHz and has VSWR and antenna factor values typical for log-periodic measurement antennas.<\/p>\n

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.<\/p>\n

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 \u00bc\u201d thread on the bottom of the mounting adapter makes it easy to connect it to most standard tripods.<\/p>\n

The TBMDA3 is shipped in a robust carrying case, as pictured above.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
