Tekbox TBMA4 double ridged horn antenna
Details
The TBMA4 from tekbox is a double ridged horn antenna with a frequency range of 1 GHz - 8 GHz and a maximum input power of 100 W. The TBMA4 is specifically designed for use in CISPR 16 EMC pre-compliance testing above 1 GHz and can also generate a defined field strength. Most other double ridged horn antennas are quite costly and don't have such a high frequency range.
The TBMA4 comes with a pistol grip tripod which, because of the 1/4" adapter thread, can easily be swapped for another tripod such as the TBTP2B, TBTP1, TBTP3, TBTP4, TBTP5 or TBTP6.
