The TBMA1 is a small, lightweight, wideband biconical EMC/EMI measurement antenna.
With its moderate price, it is ideal for radiated noise EMC pre-compliance testing and for generating a defined field strength.
It is characterized from 30 MHz to 1 GHz and has a directional pattern similar to a dipole.
The TBMA1 comes in a solid beech wood case, together with a “pistol-grip” tripod. A standard ¼” thread makes it easy to connect it to most standard tripods.
The elements are corrosion resistant and constructively locked against rotation. They are fed via a wideband balun with 2 W power handling capability. Furthermore they are protected against build-up of static charge.
