# Range extender

{% embed url="<https://www.youtube.com/watch?v=cCt2DZoJGdQ>" %}

The Range Extender allows you to place an antenna inside a confined space, improving the radio link and eliminating the need for the pilot to enter the confined space whilst piloting the drone.&#x20;

The Elios controller has been modified with antenna connectors. This modification allows the possibility to connect antennas directly to the controller or to connect the 20m extension cables when using the Range Extender.

{% hint style="info" %}
The product is compatible with **Elios 1\***, **Elios 2\***, **Elios 2 RAD** and **Elios 3**

*\*For Elios 1 and Elios 2: It requires a Flyability modified remote controller*
{% endhint %}

{% hint style="warning" %}
Do not power the Range Extender controller without antennas or cables attached. Doing so may result in serious damage to the Range Extender controller!
{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://knowledge.flyability.com/accessory/range-extender.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
