Tekbox TBMA3
250MHz? 1300MHz Logarithmic Periodic Antenna

Tekbox TBMA3 250MHz - 1300MHz TBMA3 Logarithmic Measurement Antenna
The TBMA3 is an affordable log-periodic measurement antenna aimed at 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 of 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 to 1 GHz, CISPR 16 requires the use of log-periodic antennas (log-periodic antennas) for radiated noise measurements. The TBMA3 is a medium-sized logarithmic-periodic antenna with its radiating elements and supporting booms made of powder-coated aluminum alloy. It is equipped with a standard N socket and is supplied together with an antenna bracket and a mounting adapter. A standard ¼ inch thread on the bottom of the mounting adapter makes it easy to connect to most standard tripods. The TBMDA3 comes in a sturdy carrying case as pictured above.
