# 13.5 Plugins Library

# 13.5.1 Antenna plugin elements

To create or modify a library element containing parameters of a particular antenna, select the **<span class="fabric-text-color-mark" data-renderer-mark="true" data-text-custom-color="#000000">Antennas</span>** command from the **<span class="fabric-text-color-mark" data-renderer-mark="true" data-text-custom-color="#000000">Library pull-down menu</span>** or directly with **<span class="fabric-text-color-mark" data-renderer-mark="true" data-text-custom-color="#000000">CTRL+SHIFT+A</span>**.

Since the antenna is implemented as a plugin, it is possible to include a new antenna plugin using the .jar installer and to add it to the list of existing pre-defined antennas. Any of the antenna elements is then selectable as shown in the picture below:

When adding a new antenna, enter the name (unique identifier) and description of the antenna as well as its technical parameters - peak gain and one or more radiation patterns, as necessary. See Annex A11.6 for further details.

**Note 1:** It is possible to quickly see the antenna pattern with mouse-over capability on top of the pattern button.

# 13.5.2 Coverage radius plugin elements

To create or modify a coverage radius element, select the **Coverage radius library** command from the **Library pull-down menu** or directly **CTRL+SHIFT+C**. This activates the Coverage radius library window which displays a list of existing Coverage radius options:

# 13.5.3 Propagation model plugin

To create or modify a library element containing parameters of a particular propagation model, select the **<span class="fabric-text-color-mark" data-renderer-mark="true" data-text-custom-color="#000000">Propagation model</span>** command from the **<span class="fabric-text-color-mark" data-renderer-mark="true" data-text-custom-color="#000000">Library pull-down menu</span>** or directly with **<span class="fabric-text-color-mark" data-renderer-mark="true" data-text-custom-color="#000000">CTRL+SHIFT+P</span>**.

Since the propagation models are implemented as plugin, it is possible to include a new propagation model using the .jar installer and to add it to the list of existing pre-defined models. Any of the propagation models is then selectable as shown in the picture below:
