The TBMA9 is a broadband, double-ridged MIL-STD horn antenna, designed and manufactured to offer stable linear polarization over the frequency range of 200 MHz to 2 GHz. Providing high and nearly constant gain across the operating frequency range, the TBMA9 horn antenna serves as an alternative for biconical and log-periodic types in EMC testing setups. It is optimized for both radiated emissions and immunity measurements, and can sustain a continuous RF input of 500 W during immunity tests.
The TBMA9 is made of lightweight aluminium sheets. The TBTP6 fiberglass tripod is recommended as a mounting option. A 22mm stainless steel shaft at the rear of the antenna enables rotation to set up the desired polarisation. Furthermore, there is a mounting panel at the bottom of the antenna.
