Do I need cable to view local news

Yes it is called "DTV" digital television, you will need a tv, the tv must have a digital tuner built in most do now a days, if your tv is older you will need a digital converter box also, you can go down to your local store to find a digital antenna- take it home and try it. the issue with this is you can get all channels perfectly in one room with no problem and in the next room with the same exact equipment you wont get any or very little channels, unlike traditional analog television digital television either works or not, no sketchy picture- best advice is to buy a set up from a store that allows returns and try it, if it don't work try a different antenna, also try moving it around, keep in mind you will interfere with the signal so if it works take a seat in you chair it might interrupt the signal--Good Luck.
