CLF files are distributed in a secure binary format. The data can be viewed with the free CLF viewer which you can download. This software will open CLF files and display the data both numerically and graphically. A typical screen capture is shown below. The viewer allows directivity data to be shown as 3D balloons,  as horizontal and vertical polars or as balloon spectra. Other frequency dependent data, such as impedance, Q etc. can be plotted graphically. Many data items may have further explaning info and a dedicated pdf or text info-file may be included.

Note: displays use the native decimal character, in this case comma
