Adding antenna patterns

Antenna radiation patterns

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).

Feature ADF ANT
Access PUBLIC PRIVATE
Azimuth 360 rows 360 rows
Elevation 360 rows 360 rows
Metadata Name, OEM, Description Name
Frequency Defined range ONLY Any
Gain Defined gain only Any
Polarisation Defined only Either
Tilt At time of use At time of use
Rotation At time of use At time of use

In summary: ANT gives greater freedom but is risky. ADF ensures correct inputs.

Finding a pattern

There are thousands of antennas from over 21 OEMs. To find the ones you need/want, use the database search feature by firstly typing in your frequency eg. 100 (MHz) and clicking search to filter the results and finally typing into the search box eg. Dipole to find the closest match. You can sort results by any of the columns by clicking it. Next click the hear to add it to your favourites. It will then become available in the interfaces in your selection.
This is unrelated to the API which will let you use any pattern if you know the ID number (in the table).

If you can't find your pattern you can source it from the manufacturer in ADF / NASM format.

Upload a public ADF pattern

Method 1: Login to the web interface then click the antenna database icon within the 'Antenna' input menu.
Method 2: Login to the web interface then visit https://cloudrf.com/antennas

Click the 'Add public .ADF pattern' link to access the form and then upload your ADF pattern. Any formatting errors will cause a failure which you will be notified of. Ensure your ADF data contains valid metadata in the header eg. gain, name, description. Any data deemed erroneous or inappropriate will be removed from the system without warning.

Upload a private ANT pattern

Method 1: Login to the web interface then click the 'My Patterns' button in the Antennas menu
Method 2: Login to the website then click 'Antenna patterns' on the homepage

Click the 'Add private .ANT pattern' link to access the form and then upload your ANT pattern. Any formatting errors will cause a failure which you will be notified of. Ensure your ANT data contains 720 rows of data (Azimuth followed by Elevation). Do NOT apply rotation or tilt as this is done dynamically at the time of use. Any data deemed rotated, tilted, erroneous or inappropriate will be removed from the system without warning.

Using patterns

Your uploaded pattern won't appear in the web interface immediately. You must reload the list with the reload button next to it, especially if you've just updated your favourites.

Old ANT patterns

Don't worry they didn't get deleted. You can find a list of them here.
