Library: Antenna elements
To create or modify a library element containing parameters of a particular antenna, select the Antennas command from the Library pull-down menu. This activates the Antenna Library window which displays a list of existing antennas (if you have not created any antennas before, it will show just the DEFAULT one as shown in the picture below:
This window provides the following functions:
- To create a new antenna, click on the Add button;
- To edit an existing antenna, select it in the list and click on the Edit button;
- To delete an existing antenna, select it in the list and click on the Delete button;
- To duplicate an existing antenna, select it in the list and click on the Duplicate button. Reference of the new antenna is derived from the reference of the selected one by incrementing the integer suffix of that reference, if any, or adding character '1' to the end of the original name.
When pressing the Add or Edit buttons, the Antenna editing window is displayed, where user can enter the name (unique identifier), description of the antenna as well as its technical parameters - peak gain and one or more radiation patterns, as necessary:
Note: If none of the radiation patterns is checked, the SEAMCAT will assume this being an omni-directional antenna.
Saving the newly created antenna element is done by pressing OK button. The new element will appear on the list of library antenna elements and may be used for insertion in scenarios using this name:
