Antenna with 1.5 m cord.
The antenna should be mounted outside the unit.
The antenna should not be mounted against any metal area or metal items as this will shield the signal.
The antenna should be mounted as central as possible. This to achieve the best signal all over the house.
If needed an extension cord is available as an accessory.
In the delivered HERU the antenna is already included and connected.

The antenna is also included in the Control Kit for HERU.
