The Samsung LN46B550 definitely has an ATSC tuner. With no external antenna you will get nothing. If you have anything like an old FM antenna or rabbit ears or old UHF bow tie or loop antenna, string it up in a window that faces the CN tower and you'll at least get CBC. In setup make sure you're in AIR or Antenna not Cable when you do the channel scan. CBC will show up as 5-1. When you see the OTA picture, you'll want more.

Thanks for the responses. I appreciate everyone's help.

I am just a little confused though.

I am currently able to receive some SD channels with my TV. So my TV already has an antenna. So why would I not be able to receive HD channels?
Is there a difference between the TV's internal antenna, and the antennas that people buy or make themselves?

Thanks.

Analog and digital TV signals are broadcast from the CN Tower. You're close enough that you'll be able to see some analog signals (which are currently broadcast at higher power than digital). As most transitional digital signals are much lower power, they are more difficult to receive and thus require an actual antenna.

As mentioned by Hugh, I suggest doing some reading here at DH--specifically threads that relate to reception in your area. The answers to your questions are already here....

I don't think newer TV's have internal antennas :confused:

I think your confusing SD as being analog and HD as being digital. I really thing you should follow Hugh's post and do some basic reading to get a better understanding of OTA reception and the differences between digital and analog reception.

Hi Ishi;

When you plug your cable line in and try to use it like an antenna the only channels that will show up are the analog ones. What you need to do is get an antenna, be it an out door or a small indoor one,(Canadian Tire sell RCA indoor antennas that will at least give you a sample taste of what OTA is like), and try scanning again. The reason is simple, your cable line your using does not act like a UHF antenna, nor does your TV have a built in antenna.

I like most other members suggest you take a few minutes and look through the forum headings and you will find an answer to almost any question you have starting up.

Good luck, I think withing a week or two you'll be looking at an outdoor setup. ;)

Closing. As noted please read the intro

I am having an issue getting reception on HD OTA in Toronto. The only channel I can pick up is CBC, which is on the same towers as others but this is the only one I get. Any idea why this might be?

Thanks

Your location is where?, post your tvfool report, and be aware that CBC-DT is the most powerful of all TO stations.

What antenna are you using? Indoor/outdoor?

As you can see we need a whole lot more information from you. Please read the OTA FAQ to get up to speed on OTA and how to use this forum to its best:

See the toronto reception results thread to discuss reception in the GTA.

I just bought and installed the TERK CFDTVO omni-directional amplified flat outdoor antenna which is installed about 35 feet above the ground (about 2 ft above the peak of my roof). I only get about 3 out of 7 channels that are crisp. I live in the Metcalfe area and was wanting to know if there is a better antenna that will get me a better choice of channels and to have them all crisp. I've seen ones that work on a remote control to direction the antenna and others that are fixed as well as the one I just installed that is multi-directional. So, any info you all could share with me would he great!
Thanks.
