When selecting a type-13 file, remember that the pattern shape, the forward gain, and the elevation angle are more important factors to consider than the name applied to the array. The goal is to match the type-13 file to your best estimate of the performance of your own array or antenna. The sample patterns in the linked gallery of model plots can go a long way in assisting in the selection. If a closer approximation is required by a specific application, then you should consider modeling your actual antenna or array.
One way to simplify the file structure within your version of VOACAP is to download only the collection (or collections) that have the most promise of closely matching your station antenna (or antennas). Unzip the files into a separate hard-drive directory. Then copy only the relevant files to your directory within the VOACAP program. You may rename the files within the 8-character limit, retaining the extension. As well, you may open the files within Notepad or Wordpad and revise the top line description to suit your needs. However, do not disturb the format of the remaining lines of the file.
These notes are no substitute for mastering your particular VOACAP software. Moreover, the collections are made available without charge and without warranty. Use of the files is the sole responsibility of the user.

Why Maintain This?
Cebik's website was a treasure trove of information one could spend hours exploring, reading, and learning from.
The original Cebik website disappeared at some point, along with the antenneX site around 2017 which offered for purchase various books and modeling file sets that were referenced throughout the website.
-Marcel De Canck ON5AU (SK) made available a copy of Cebik's website, some books, and magazine articles at www.on5au.be. Marcel also wrote several books including Advanced Antenna Modeling, and was close friends with John Devoldere ON4UN (SK) who wrote ON4UN's Low Band DXing Book. For anyone interested in these subjects they are both well worth getting.

Regrettably Marcel also became silent key in October 2023. Not knowing what might happen with Marcel's website I made a snapshot of it, and started looking at the Cebik Pages..
