The TBMA1 (30MHz – 1GHz) is a small, lightweight, wideband biconical measurement antenna. With its moderate price, it is ideal for radiated noise EMC pre-compliance testing and for generating defined field strength.
It is characterised from 30MHz to 1GHz 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 1/4 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 2W power handling capability. Furthermore they are protected against build-up of static charge.
