Electronic – the difference between a tuner and an antenna

antennafrequencyRFtv

I was just told by my TV's customer service that my TV had a tuner but no Antenna as a response to my question – Can I use my TV's inbuilt Antenna to pick up over the air channels?

I was wondering if someone can elaborate on what the differences between these are.

Thanks and please let me know if this is not the most appropriate forum to post it on; I can prob move it

An antenna is an aerial. A wire structure which, to pick up TV signals, is typically mounted at the highest point in a house and connected by a coaxial cable.

A tuner is a circuit that selects a particular signal from all those received by the antenna. Typically this is by tuning to a specific frequency.


Some small portable TVs do have a small antenna as a part of them, the older ones would take the form of an external wire loop with or without telescopic elements. I'm not aware of TVs with completely internal aerials. Perhaps they exist but I imagine reception would be very poor.
