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 typesLink to Available antenna types

Antennas vary in two parameters : ingress protection and gain.

Ingress protectionLink to 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.

GainLink to 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.
