An HD antenna won’t give you all of the channels you would have access to if you purchased a cable subscription. However, it will increase the number of channels you can watch on local TV. And the one-time cost (as opposed to an ongoing monthly fee) means you’ll save money. It can be another attractive feature of using antennas to expand your viewing choices.
There is NO WAY to get FREE CABLE TV over the air, with an HDTV antenna. It is not possible to get HGTV, The History Channel, AMC, CMT, TVLand, and those other types of channels over an HDTV antenna! I wish these websites and these phony ads would stop fooling people into buying these “magic sticks” and “magic TV” antennas claiming that they will be able to watch CNN, TNT, TBS, The Science Channel, Biography, National Geographic, etc. without paying a cable company. It is NOT TRUE. They can stream whatever with a subscription, but guess what? THEY STILL NEED TO PAY THE CABLE COMPANY FOR INTERNET ACCESS AND THAT COSTS ABOUT $80 A MONTH WHEN YOU CANCEL THE BUNDLES!
