What is an ANT file?

ANT files mostly belong to Ubiquiti UniFi Controller. ANT files store antenna radiation pattern data that detail an antenna's directional gain and field distribution. These files are used to define how antennas transmit and receive signals in various spatial directions.
They are commonly integrated with systems such as the Ubiquiti UniFi Controller (more details here) to optimize network performance by accurately representing radiation profiles.

The files can contain data points, including angular measurements and gain values.

They are sometimes encoded in UTF-16 (Little Endian), making a text editor that supports this encoding useful for review.

Software like Antenna Magus may also use these files in antenna design workflows.

In isolated cases, they serve as technical documentation, as seen with certain Brazilian Navy implementations.

FilExt.com note: To open and view an ANT file, use the corresponding network management or design software. Alternatively, a text editor that can handle UTF-16 can display the file’s contents.

How to open ANT files

You need a suitable software like Ubiquiti UniFi Controller to open an ANT file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your ANT file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a ANT file directly in the browser:. Just drag the file onto this browser window and drop it.

ANT file format details:

If you can determine the file format, the associated program can also be determined. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. File extension, signature and file format must match; otherwise errors will occur when the file is opened. Knowledge is power - this also applies when dealing with unknown or faulty files. In the following you will find our evaluation of the ANT files:

The file type with the extension 'ANT' is used by a few programs, each with its own file format. The file formats most commonly found in ANT files are:

• 30% of all ANT files do not have a uniform signature. The content also consists of readable text fragments, which can be viewed with the help of a text editor. The average file size is 4 KB with most files being between 4.3 KB and 4.8 KB in size. The file type is relatively new. The following filename is common: UAP-AC-Pro-2G.ant or UAP-nanoHD-5G.ant. Such files sometimes refer to mesh and lite.
• 9% of all ANT files use the same file format, which can be identified by the letters "0.0" at the beginning. These files contain text and words as well as binary data. ANT files can be up to 6 KB in size, but are often around 2 KB - 6 KB. The keywords -12.47 are typical for these files. The following filename is common: antenna_pattern_20180601.ant. Files like these have the following tags: pattern, telewave and antenna.

The remaining 61% of all ANT files are different files with different signatures, often, for example, General. They are often associated with page, pgad, labelitaly or port. You can get all the details of your ANT file by dragging it onto this page or by clicking the button "Choose your .ant file to analyze" above.
