The X-Wing BiLog for RF EMC immunity testing

The combination of BiLog® technology with novel low frequency, folded elements (X-Wings®) allows low frequency power to be efficiently projected forward without significantly affecting the high frequency elements.
The CBL 6144 gives an incredible antenna factor of only 3dB at 26MHz together with a useable VSWR making
the CBL 6144 able to deliver 10V/m with 80% AM modulation using an amplifier power of less than 500W# at 26MHz.

High Power Handling

The CBL 6144 has been optimised for immunity testing to IEC 61000-4-3, and uses a high impedance balun, giving a considerably improved VSWR at low frequencies over the original immunity BiLog® CBL 6121A. Although it is larger in size than the classic emission BiLog®, it is still smaller than any conventional
alternative. The CBL 6144 can handle powers up to 600 Watts and is suitable for testing in most shielded rooms and anechoic chambers. The CBL 6144 covers the requirements for testing medical equipment to EN 60601-1-2 and FDA (in the US) for RF immunity.

Axial Rotation

The CBL 6144 is supplied with a mount to fit most standard fixings, set at its mechanical balance point. An optional rotating mount, CHA 9440A, can be supplied separately for mounting to box section tower booms.
Although primarily designed as an immunity antenna, the CBL 6144 can be used for emission testing and is supplied with individual calibration data.
