If you mean free Over the Air (OTA) TV using an antenna:
1) If you have an HD TV set, you don't need any kind of special box.
2) If you don't have an HD TV set, but your TV set has a digital tuner, you don't need a special box, but you will see the HD picture converted to a Standard Definition (SD) picture.
3) If you don't have an HD TV set and your TV set does not have a digital tuner, you will need a converter box. The converter box will convert the HD broadcasts to SD so your TV can display them.
If you mean cable TV, it depends on your cable provider and your TV.
If you don't have an HD TV, at best you will see an HD signal converted to SD.
If your TV has a digital tuner and it is also a QAM tuner, you might be able to receive some HD channels without a box if your cable company chooses to provide unscrambled HD channels. If your TV has an analog tuner or a digital tuner without QAM, you will need some sort of box.
There are several alternatives to cable for HD television. They are dependant on the television and also the location.
Terrestrial broadcasts are now being offered in HD. A television with an HD tuner needs no other equipment to receive HD terrestrial broadcasts but a digital HD terrestrial receiver box may be needed.
Most areas have satellite coverage. Sky in the UK and Dish Network in the US are two examples. The UK also has the Freesat service - a free satellite service that includes SD and HD broadcasts. A suitable satellite receiver is needed but there is no subscription to be paid.
Cable providers provide competitive services to terrestrial and satellite broadcasts but almost all demand a monthly subscription. Depending on the location, satellite and terrestrial broadcasts offer free to air services as well as subscription channels.
Local television retailers will be able to advise on the availability of broadcasts in your area but be aware that their intention is to sell equipment and sesrvices to you so their advice may be biased towards subscription based solutions.
