I want to connect an aerial to my Truma iNet Box – what do I have to consider?

Since an aerial is already integrated in the Truma iNet Box, you generally do not need an external aerial. Remember that reception could even become worse if you connect a wrong aerial to the Truma iNet Box.

However, if you still want to connect an external GSM aerial, it must comply with the specification in the operating
instructions. There must be a gap of at least 20 centimetres between the aerial and people. If an external aerial is connected to the iNet Box, the switch beneath the aerial connection must be set to “ext.”. The internal aerial is then switched off.

Please contact your Truma Partner if you decide to connect an external aerial.
