Tekbox TBMA2 bikonisk antenne 30 MHz– 300 MHz

The TBMA2 is a biconical measurement antenna for EMC radiated emission testing and generating defined field strength. With its affordable price it is an excellent choice for any lab carrying out in house pre-compliance testing.

It is characterized from 30 MHz to 300 MHz and has a directional pattern similar to a dipole antenna.

The TBMA2 comes with a POM bracket with a ¼ " thread insert for mounting the antenna on standard tripods (Not included)

The TBMA2 radiating elements are made of stainless-steel parts to avoid the disadvantages of contact degeneration over time, which are associated with non-welded designs using aluminium. The radiating elements are not welded but fastened with grub screws, which makes assembly / disassembly simple and makes the antenna easily storable and transportable.

The antenna elements are fed via a 1:4 balun with 100 W power handling capability.
