## 📍 What You’ll Do

* Add antennas, dishes, GPS units, and other equipment to your structure
* Place them at the correct height, azimuth, and position
* Assign tenants (e.g., Telia, AT\&T)
* Add linear ancillaries like feeders and ladders

## 🛠️ How to Add Equipment

1. Open the structure we just created by entering it from the all structures view.
2. Navigate to the `Ancillaries` page. You'll see the option of adding discrete ancillaries (antennas, RRUs, lightning rods etc), and linear ancillaries (feeders & access ladders).

3. Let's add some antennas. Press the `Add discrete ancillaries from database` field and search for `Ericsson`. You can also search for a specific ancillary type, like `RRU` or `GSM`.&#x20;

You can add your own ancillaries to the database in the `Database` tab. There, you could also specify your own custom force coefficient, or calculate the force coefficients from wind tunnel data.
{% endhint %}

4. As you antennas, you'll see the possibility of specifying the tenant, its status, precise positioning and more.
5. Moving to the `Linear ancillaries` tab, you'll see the opportunity to add both feeders and access ladders.&#x20;

{% hint style="warning" %}
We use force coefficient 1.2 for feeders and 2.0 for access ladders.&#x20;
{% endhint %}

## Importing Ancillaries From Other Sources

If you already have ancillary information structured in, e.g., Excel, you can directly import this onto your site. Have a look at [this blog post](https://www.shapemaker.io/blog/importing-discrete-ancillaries-to-sites)!

{% hint style="success" %}
To re-use common ancillary configurations, use the Ancillary Groups functionality found in the top right corner.&#x20;
