Three Antennas In One The CBL 6112 operates over the unprecedented, wide range 30 MHz to 2 GHz. It effectively combines the performance of three standard EMC antennas, the Biconical, the Log Periodic and the Waveguide Horn. Considerable savings in the order of 40 - 50% can be made in expensive test time, plus the added benefit of improved repeatability and reliability by not having to laboriously disconnect and reconnect antennas during testing.
