no you need the box
Comcast will provide you with a digital tv box that allows your television to receive the digital signal and therefore you won't need the digital tv antenna.
Digital antennas can be installed by yourself. However you need to check zoning laws to make sure that you can have an antenna.
In the US the answer is probably not. Digital and analog TV broadcasts use the same frequencies and antennas. Digital TV is more fussy about signal quality than the older analog signals. So if you get marginal analog reception, figure on getting a new antenna for digital. The idea that there are special HDTV antennas is just marketing hype. Any antenna that gives you better digtial reception will also give you better digital reception.
A tv antenna and a digital tv and/or a converter box.
It sure will! (But you still need an antenna)
All TVs including new ATSC Digital ones use the same frequencies as older NTSC Analog sets. An amplified antenna is recommended because there is a threshold where a weak analog signal will be visible (with considerable static) but a digital tuner will not have sufficient strength to display a digital (no noise or static) picture. Outdoor roof Antennas work great as well, you don't need an HDTV antenna, discount stores should have one for around $30.
No. There will be no analog signal to receive and process from the outdoor antenna. The only signal coming from the outdoor antenna will be digital. When the conversion is complete. You will need to hook up your antenna directly to the TV. Your conversion box will be worthless as far as analog to digital is concerned.
All TVs need a antenna of some type whether it be a set of rabbit ears, a roof top antenna, cable or sat. decoder.
Depends. Do you need a converter box to hook up the TV to the antenna? No. You just connect the antenna to the TV's antenna input. Do you need the converter box to see "X" channel? Maybe. If "X" isn't broadcasting "over the air" in your location, then you will need a) cable or satellite service and b) the converter box.
The only time you will be in need of a digital converter is if you currently own an analog television that is connected to an over-the-air antenna signal.
You don't need a new TV or antenna. You need a Digital Converter Box. Go to a Radio Shack, Circuit City or Best Buy. Connect your old antenna to the converter box, connect the converter box to your old TV...all will be well.
No, most projectors do not have TV tuners. You will need to connect the antenna to a digital TV tuner, and then connect the tuner to the TV.
