I want to develop DAB+ active antenna circuit power supply.

I use active antenna like on attachement "dab_antenna.jpg". There is no extra wire so 5V is given via SMB central pin.

In dab module of different manufacturer I have found that 5V VCC is given directly to signal wire (like on picture "active_antenna_voltage.jpg").


My question if is it is possible also in si468x chips? Can I supply DAB antenna like this idea (picture: si468X_active_antenna.jpg) or there is better way?
