i have cable modem with OOL. the CATV is cablevision.

Why bother? You can construct your own simply antenna for a few cents worth of wire and it'll often be superior to what you can buy in the stores for $50. You'll need 8 thumbtacks, a 75ohm-to-300ohm impedence matching transformer ($0.75 if you don't already have one), and about 15 feet of solid core, insulated wire. Here's how to do it:
Arrange your thumbtacks in a grid:
1 2 3 4
5 6 7 8
Now, connect the numbers in the following order: 7, 3, 4, 8, 7, 3, 2, 6, 5, 1, 2, 6, 7
I threw together a quick sketch here. Be aware that these are supposed to be squares. The lines are slanted in the sketch just to illustrate how to loop the wires.
How big to make the loops? That depends on the channels you're going to watch. More specifically, it depends on the wavelength of the channel's broadcast. Here's how to calculate it:
Frequency of channel = 386 + 6*(channel number)
example: channel 18 => 386 + 6 * 18 = 494 MHz
example: channel 62 => 386 + 6 * 62 = 758 MHz
Wavelength (in meters) = 300 / frequency
example: channel 18 => 300 / 494 = 0.607 meter = 23.9 inches
example: channel 62 => 300 / 758 = 0.396 meter = 15.6 inches
Take the average frequency of the channels you plan to watch and divide this by two. This is how big to make your loops. It's pretty forgiving, though. My current antenna is roughly a full-wavelength instead of half and only has 2 loops instead of 3 but the results are still cable-quality unless there are storms in the area. Whatever length you pick, though, you must make sure each loop is exactly the same size.
You don't need thick wire for this. You should be able to use 38gauge or finer laminated magnet wire. Just make sure your wire is insulated because the the wires cross paths a few times in the antenna design. In fact, if you use magnet wire, you could probably attach it to the wall and paint over it and never know it's there.
In theory, this antenna design offers around 12db gain. Not bad for a few minutes work and less than $1 worth of materials.

with comcast you can.

I have Comcast and it wasn't possible when they turned me off sometime last year. Since I've lived here, the cable company here has changed ownership at least a couple of times. I don't remember what the company was originally when I moved here.Originally posted by: Lifer

any details on this? does comcast operate differently?
what channels are you getting?

The equipment for any given cable company probably varies with area.

I am pretty sure that you will not get any channels at all if you cancel your cable TV service.
I think the cost for OOL will also increase if you don't have cable TV.
In some systems/parts of some systems, if you subscribe to cable modem service, they don't filter out the sub-basic ($8-12/mo) cable service, so you can enjoy that for free sometimes. The equipment that serves my apartment building is an example.
ATT/Comcast figured this out and raised the cable-modem rate $15+ if you don't subscribe to cable TV. Since Basic Cable is only $6/mo in my area, I had no choice but to subscribe to their TV service.In some systems/parts of some systems, if you subscribe to cable modem service, they don't filter out the sub-basic ($8-12/mo) cable service, so you can enjoy that for free sometimes.
