Yes you can. First, you have to carry out the channel search with Antenna and repeat it with Cable.
Your TV has an integrated tuner that enables you to view free cable (or digital DVB-C) channels from the cable provider and free-to-air antenna (or digital DVB-T) channels. It is not possible to watch both DVB-C and DVB-T channels at the same time. When you switch between the respective networks, you will need to switch the corresponding antenna cables as well.
To watch the channels from each installation, you need to switch between Antenna (DVB-T) and Cable (DVB-C) in the TV's Menu.
