You can use ADF / NASM (TIA/EIA-804-B standard) and ANT patterns in CloudRF.
These basic text formats are open and easily edited and will display a patterns azimuth (Horizonal plane) and elevation (Vertical plane), typically as 360 rows of data each.
ADF pattern data is generally in dBd and ANT is a normalised range with 0 as peak power.
ADF is the primary pattern format and all ADF patterns are public (accessible to all users).
ANT is the secondary format and is private (accessible only to the uploader).
