Your TV is less than 5 or 6 years old, should have a digital tuner built in.
Generally, indoor antennas do not work too well here as signal is not great in the first place - you may get something, but you are unlikely to get most /all.
As Marcliff states - if you are on a community, it is the legal requirement of the community to provide the TDT, or at least to the nearest point in the street outside your property. May just need a cable connection.
If no community system - 3 prong decent antenna on the roof, pole mounted usually. We can do these type of works - community and private.
