Tekbox TBMA7 Log Periodic Measurement Antenna
Log periodic measurement antenna for EMC pre-compliance testing with 150 MHz–3 GHz frequency range, 50 Ω impedance, N-type female connector and carrying case.
The Tekbox TBMA7 is a logarithmic periodic measurement antenna designed for radiated emission EMC pre-compliance testing. It covers the frequency range from 150 MHz to 3000 MHz and provides VSWR and antenna factor characteristics typical of logarithmic periodic measurement antennas.
The antenna features radiating elements and supporting booms made from aluminium alloy, providing low weight and high mechanical stability. The TBMA7 is equipped with a standard female N-type connector and is supplied with an antenna bracket and mounting adapter.
The supplied mounting adapter incorporates a standard ¼-inch tripod thread, allowing easy installation on most standard tripods. Positioned at the antenna's centre of gravity, the adapter can be tilted for flexible positioning during EMC measurements.
The TBMA7 is supplied in a robust carrying case for safe transport and storage between test locations.
