Skynetlink is not terrestrail TV, it is broadband or wi-fi. The terrestrial channels for Spanish TV (TDT) can only be received with a TV aerial. Either communal or private. You should have an aerial socket on your wall (we have two, one marked TV and one marked radio). You need to connect that socket to your TV. Look in your instruction book and see how to receive TV but without an aerial you won't get anything.

All modern TVs have a digital receiver built in and you simply set up your TV as shown in the TV guide (normally Menu, digital setup and carry on from there). If you have an older type TV with no digital tuner then you need a box similar to a freeview one from UK (TDT receiver in Spain).

It's the aerial that's important, though. If you are quite high up you may get some channels with an indoor aerial but most places need a roof aerial.

Before we moved to our present flat we used an active antenna to receive Spanish TV without an external antenna.

It came from a Carrefour hypermarket.

As well as being an antenna it has an RF amplifier in it and has a power supply which needs pluging in to a wall socket.. I was sceptical when I was originally told about them, as we could receive nothing with an ordinary set top Ae.

You may have to move it around the room for the best signal (away from the metal in the reinforced pillars of modern buildings) but we received all the Spanish channels from two different transmitters.
