New TV- Not Quite Hi Def...
I had looked into the issue of antenna reception a while back, and had read that there was no such thing as a digital antenna. The rule of thumb is that those that get decent analog TV reception should do fine with digital as well (www.antennaweb.org is a rule of thumb for what channels you should expect to get, and I expected several). Good enough, I figured as I get all the analog channels without too much difficulty. However, there was a crucial detail that I didn't realize, and now is a lot more obvious with some searching.
Anyway, I hooked up the set, and plugged in my rooftop antenna. I did a channel scan, and it found the usual analog stations, plus brought in three UHF stations with tons and tons of fuzz. Curiously (more on this later), I had one channel, ABC in digital glory. Actually, it kept pixelating every few seconds and dropping out. Outside, it was raining pretty hard so I figured I'd have to redo the channel scan in better weather. Curiously, the analog version of ABC didn't look so different to the digital version, except for the pixel pattern being a digital exclusive.
A few hours later, the rain stopped, and on the channel scan there were no digital channels! Hmmm- this is not what I expected. Like any self respecting TechNudger would do, I turned to the internet. Before I asked for some sagely Oldster advice (who has fiberoptic deliver his TV these days), I looked into some forums. When I searched through these threads, I started to realize that my venture into digital content was grounded from the start. I learned that the hi def content is sent over vacant UHF channels, not the VHF frequencies, that we better know as the 2 through 13 channels. The problem is that my antenna is the classic 70's model that only tunes in VHF and not UHF. When I picked up the digital ABC one, due to some weather anomaly, that was the exception, and not the rule (that I haven't been able to duplicate, FYI).
The bottom line is that without a newer antenna, made to bring in the UHF signals, there will be no high definition content on the new set. Thankfully all is not lost. The Samsung set does have an analog tuner as well. While it does not have the perfection of a digital signal, the TV is still perfectly watchable. For the time being, I plan to research and save up for a new antenna. I'm just glad that I started the switch to digital TV this early because it got a little more complicated than I would have expected. At this point you can count me in with the 15% of Americans with an HDTV, but remember that 47% of us don't have any hi def content on it- yet.

First - rabbit ears will pick up HD channels. I guess the tech term is Bi-Polar or something like that. You can pick up an antenna at Wal-Mart for around $30-$40 that will do good as long as you are not a HUGE distance away from stations. I gotthe highest DB rated one they had by Philips and it does a decent job. I am pretty far away from some stations though ( 36 miles ), so I do not get perfect coverage all the time! I followed antennaweb.org, and it didnt help what so ever! I have my antenna pointed in a direction taht they say doesnt even have any channels to pick up, just to get the closest ones and a couple farther away :/. I might invest in an outdoor antenna if I can find a company that can guarantee me the reception I want.

I picked up the closer hdtv channels with just an old set of rabbit ears! Try it, you might be surprised ;)
That forum you checked into was not exactly correct. MOST of the digital stations are on UHF, but not all. In my area we have one on channel 4 and one on channel 10.
I am assuming that the TV antenna you pictured was not the one on your house. I say that because that antenna appears to be a UHF/VHF combo antenna. The UHF portion would be on the left. The two sections forming a V are a UHF corner reflector type of antenna.
Beware any antenna with a mast mounted amplifier or preamplifier. These worked well with analog signals but tend to perform poorly in the presence of strong UHF digital signals. They become overloaded and actually degrade the performance of the antenna.
Thank you both for your insightful comments. I am around 25 miles away from the transmitters, and at the bottom of the hill so I'm pretty sure I'll need a new roof top model of antenna.
Yes Gyro, very astute. I was too lazy to go outside and take a picture of my antenna, and I was wondering if anyone would have noticed that.
