Connecting Terrestrial TV with Room Antenna: Digital LCD TV, SAT Socket, Decoder, and WiFi

Hello, Is anyone able to answer the question of how to connect the TV, to any source of vision? the situation is such that while performing work on the object (WiFi installations) we were asked to connect the TV, it would not be a problem if not that the TV-SAT socket is deaf, ie the wire passes through some dividers and unexpectedly ends in the installation bar , we thought about connecting this TV to a normal room antenna, are there any contraindications to doing it this way? Generally, it has to be cheap about quickly. The TV is digital, ie LCD, we do not know if it has a decoder.
I will say honestly, we do not know much about this kind of work but we promised that we will try to remedy it.

I think that for a person familiar with the subject, the matter will be child's play, unfortunately we do a bit different installations and we do not have knowledge in this field.
Best wishes, Santa

Connect to an ordinary dish, eg a voltaic dish, the only condition is that the TV must have a built-in decoder, if there is no need to buy an external one.

Connecting any antenna is not a problem. The only question is whether she is able to pick something up - in addition to the room.
