TBMA2
Biconical Antenna
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.
