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<p class=\"p1\">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<p class=\"p1\">The TBMDA3 is shipped in a robust carrying case, as pictured above.<\/p>\n<h3>SPECIFICATION<\/h3>\n<ul>\n<li>Type: logarithmic periodic<\/li>\n<li>Frequency range: 250 MHz\u2013 1300 MHz<\/li>\n<li>Nominal impedance: 50 \u03a9<\/li>\n<li>Connector: N type female<\/li>\n<li>Maximum continuous input RF power: 100 W<\/li>\n<li>Isotropic gain: 6 dBi \u00b1 1.5 dB<\/li>\n<li>Antenna factor: 14.2 \u2026 27.5 dB\/m<\/li>\n<li>Voltage Standing Wave Ratio (VSWR): &lt; 1.95:1 over the entire frequency range ; 1.35:1 average<\/li>\n<li>Width: 749 mm (29.49\u201d)<\/li>\n<li>Height (With the mounting adapter): 170.23 mm (6.70\u201d)<\/li>\n<li>Height (Without the mounting adapter): 79.5 mm (3.13\u201d)<\/li>\n<li>Depth: 863 mm (33.98\u201d)<\/li>\n<li>Weight: 1.78 kg (3.92 lbs)<\/li>\n<li>Tripod Adapter Thread Size: \u00bc\u201d<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>The TBMA3 is an affordable log-periodic antenna, used radiated noise measurements for EMC pre- compliance testing.
