Tekbox TBMA1C Biconical Antenna
The TBMA1C is a small, lightweight, wideband biconical measurement antenna. With its moderate price, it is targeting radiated emission EMC pre-compliance testing and generating defined field strengths.
It is characterised from 20 MHz to 1 GHz and has a directional pattern similar to a dipole.
The TBMA1C comes in an aluminium carrying case. 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 the build-up of static charge.
