The Chase CBL 6143A is a Bilog Antenna. The CBL 6143A antenna can be utilised for E-Field emissions and immunity testing, and is also supplied with an extender rod and various options for tripod / mast connectivity.

Where would this be used? The Chase CBL 6143A can be used for Radiated Emissions in order to measure the emissions being produced by the EUT and Radiated Immunity testing in order to subject an EUT to known levels of RF signals. The folded X wing reduces coupling to the chamber floor or ceiling when in vertically polarized configuration. The extended frequency range is useful also in the receiving mode with good symmetry and a reasonable Antenna Factor at the higher frequencies.
