# Antenna

Installation and positioning of the long-range antenna

To ensure optimal communication and maximize radio performance, antenna positioning is crucial.

## Connection

The long-range antenna (**ANT REN SMA LR 868 1000-008**) connects directly to the dedicated port on the Gateway:

1. Screw the antenna's SMA connector onto the Gateway base.
2. Tighten firmly by hand (do not use pliers so as not to crush the connector).
3. Place the antenna as high as possible, ideally outside the cabinet or technical room.

## Why remote-mount the antenna?

The *gateway* being often installed inside electrical cabinets, the radio signal can be weakened when the antenna is kept inside the electrical cabinet. Remote-mounting it makes it possible to:&#x20;

* **Reduced interference** : Remote-mounting the antenna keeps it away from electromagnetic disturbances generated by power equipment.
* **A range gain** : An antenna placed outside the cabinet ensures maximum coverage for your LoRaWAN sensors.

## 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://enless.gitbook.io/centre-aide/guides-installation/documentation-en/gateway-and-receivers/rx-lorawan/installation/antenna.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.
