Samsung SIR-T451 High Definition Terrestrial Tuner
Works perfectly and digital TV is great!
I've purchased many items through amazon over the years and always read the user reviews to help guide me to the right item to buy.  So to do my part, here's my take on the Samsung T-451.   <br /> <br />This is my first digital over the air receiver so I can't really say it's better than the others.  I was a little leary about getting it simply because it's one of the least expensive ones available.  But being a miser, I went cheap, and not only that I opted for a refurbished unit.   Both turned out to be good choices.   The unit works perfect.   It arrived in a plain box, but was in new condition and included all the cables, remote and manual.   I had it unpacked and hooked up in an hour.   <br /> <br />I connected the T451 to a Dell 26\\" wide screen using the DTV component (Y,Pb,Pr) jacks plus L/R audio cables.  This works fine. The T451 and the Dell also have DVI and RGB input/outputs but I haven't tried these.  I assume I would get the same result, a perfect picture.  With DTV you get a perfect picture and sound (if reception is good enough) or nothing - no inbetween.   <br /> <br />According to both antennaweb.org and checkhd.com, I'm about 4 miles from the 6 available local DTV broadcast sites (ABC, CBS, NBC, WB, UPN, PBS).  FOX is still bargaining with the FCC for a channel.  I'm also located on a hill and can see the broadcast antennas from my yard.   Because of that, I'm just using unamplified rabbit ears for VHF and a bow tie loop for UHF.  I get all the available stations.  Luckily, the stations happen to all be in the same direction so I don't have to re-adjust the antenna for each channel.   The auto channel search feature on the T451 worked fine and picked them all up.  It's easy to add/delete channels manually if needed.    <br /> <br />The T451 is simple and easy to use.   Once the channels are set, you just power it on and use channel up/down buttons.  You can also key in the channel numbers directly.  The flaws I've found so far are minor.   As pointed out in another review, the signal strength display takes too many button presses to access.  But I haven't used it often, mostly when I first set it up.   There's no TV power button on the remote, although there are volume buttons.  That's about it for negatives. <br /> <br />In summary, I haven't been so impressed by both a specific product and also a new technology in a long time.  Digital over the air TV is amazing and the Samsung T451 is an inexpensive and completely adequate way to tap into it.   If you are used to analog TV with snow, ghosts and scratchy sound, as was I, DTV will blow you away.  And as others have said, \\"it's totally free\\", hard to believe these days.
