# Antenna

The receiver **RX HTTP** requires an external antenna to pick up signals from LoRa Easy transmitters.

## Hardware recommendations

The antenna is not supplied as standard with the product so that you can choose the model best suited to your environment. However, to guarantee optimal performance (range and sensitivity), we recommend using our certified model:

* Enless reference: **ANT REN SMA LR 1000-008**
* Type: **Remote antenna** (high gain).
* Connector: **SMA** male (to be screwed onto the female SMA socket located on top of the enclosure).

## Benefits of the remote antenna

Using a remote antenna (with cable) offers several strategic advantages:

1. **Cabinet exit** : If the RX HTTP is installed in a metal cabinet (which acts as a Faraday cage), the remote antenna makes it possible to place the radiating element outside the cabinet to maintain the radio link.
2. **Height gain** : It allows the antenna to be placed higher than the receiver itself to overcome physical obstacles.
3. **Orientation** : Makes it easier to optimize reception by adjusting the antenna position without moving the receiver.

## Radio installation tips

* **Clearance** : Avoid placing the antenna immediately near sources of strong electromagnetic interference (motors, variable speed drives).
* **Positioning** : For maximum range, install the antenna vertically.
* **Tightening** : Make sure to screw the SMA connector on by hand (do not use tools so as not to crush the connector).

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://enless.gitbook.io/centre-aide/guides-installation/documentation-en/products/rx-http/installation/antenna.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
