TV connection to satellite socket

Is this your socket?:https://imageshack.com/
This socket model was installed by UPC (Numericable) until 2001
Normally, with such a socket you should have access to a collective service from Numericable
Connect the data socket to the TV antenna socket and select 'cable' for the search, try it, if it doesn't work: 'terrestrial'

This is a good take.

So, I need an antenna cable with one end satellite and the other end TV if I understood correctly...

Yes, take a standard cable and cut one of the connectors (not the one that connects to the TV)
Then install an F connector like this: http://www.antenne-vision.com/comment-monter-une-fiche-F-ccjaaaaaa.asp
Or screw this adapter onto the wall socket and connect a standard TV cable: http://www.conrad.fr/adaptateur_fiche_f_male_fiche_coaxtv_male_p_52756_53150_834623_532531
or this type of connector: https://www.castorama.fr/fiche-femelle-coudee-connectique-optex-or-hq/3327960510293_CAFR.prd
For channel search, select 'cable' then digital or if it doesn't work: 'terrestrial' then digital
Ask your neighbors; in some cases, Numericable provides a special decoder for free (without subscription but with a deposit) that will allow you to view TNT channels on your TV
It's hard to say in what exact case you find yourself, ask your neighbors, landlord, or property manager
One thing is for sure, it's an old 'UPC' socket; the condominium must have concluded a distribution contract with Numericable for TNT via cable network (common)
This allows Numericable to more easily offer subscriptions to its services
This TNT distribution service is a 'profitable' contract for Numericable
but no subscription to pay for 'TNT' service (sometimes a decoder is necessary and is provided against a deposit)

This special TNT decoder from NC is no longer needed anywhere, since NC injects TNT signal in clear directly into the cable everywhere. TNT signal compatible with commercial TNT tuners. Therefore compatible with the Samsung monitor, through a search in digital antenna mode.

That said, I recommend a search in both analog and digital antenna mode: In most regions, there are still analog channels that could be interesting.

There are also ready-made cables, with a screw connector on one side and a smooth one on the other.
