2.4.2 Radio
The hub has an 868MHz radio to receive Wireless M-Bus frames from the surrounding sensors.
2.4.2.1 Antenna
The hub has a female SMA connector labelled “RF” on the board to connect a radio antenna. The product
is delivered with an internal antenna. An external antenna can be connected to the product. To do this,
unscrew the cap on the box and fit a M16*1.5 cable gland (not included).
To optimise the radio range, it is important to install the radio antenna as high as possible and to place
it carefully, avoiding obstacles as far as possible. As a priority, move it away from any metal (cupboard,
beams...) or concrete (reinforced concrete, walls...) obstacles as they greatly attenuate radio waves.
In the new box, the cable gland is optional and is installed after breaking the breakable part provided in
the box.
End users must make sure their installation using remote antennas meets applicable EMC
standards.
