You gateway can have different antennas connected. The software has to know about which antenna is configured to adapt the output power adequately.

By default, antenna type is not configured at all.

If the antenna type is not configured, most of the packet forwarders will not run.

Setting a bad antenna type will not damage the gateway.

Available antenna types

In v0.4.0-rc the antenna type was called "indoor" instead of 2dBi and "outdoor" instead of 4dBi.

Antennas vary in two parameters : ingress protection and gain.

Ingress protection

Indoor and outdoor antennas are available. Whether it's one or the other, this has no impact on the software and is therefore not to be configured.

Gain

The antennas are available in two different sizes corresponding to the gain:

  • 200mm (7,87 inches) : ~2dBi
  • 500mm (19,68 inches) : ~4dBi

The gain has to be configured.

Check the antenna type

The antenna type is shown on the LoRa > Status page, in the "Hardware widget".
