I just ordered a DB2. I did some digging on the Internet yesterday, and the DB2 masquerades as a DTV2BUHF. Do a Google search for that unit and get one for way less $$.
Also did some "research" on the amplified antenna thing, and I stand by my previous statements on getting a good physical raw antenna. However, there have been good points made that an amplifier in the antenna is good for overcoming line loss in long cable. That makes sense. Line loss is significant when you get up to the 30-50 foot lengths. Also, if you go through splitters that cuts the signal too.
So yesterday I built a homemade antenna using a shoebox and a cookie sheet!
I was totally shocked when I plugged this sucker in and it worked, in my basement, 15 miles from the towers! It is somewhat marginal though, that's why I ordered the DTV2BUHF. I really need to get outside with the antenna cause I have aluminum siding which makes my whole house a Faraday cage. BTW, if you make this unit, it's even easier than the instructions. Instead of the copper wire "ears" I just peeled back the shield 6" and used that!
Anyway, with my shoebox junk antenna, I had my Dish Network Vip722 scan for local channels, and this is what I get:
Out of that list it seems the only HD is one of the WPT1 channels (This is WHA, Wisconsin Public Television) Notice all the subchannels...
I am not sure if this list is a complete Madison list, because this is just a list of channels the Vip722 could pick up with the shoebox.
Anyone understand what stations are broadcasting in HD?? If you go to the Websites for the TV stations, they don't have a link that explains what all "subchannels" they have, whether it's HD, what frequency, etc... I guess this is top secret stuff. They will give you a link to the latest on Britney's sister, but don't give the dang frequency they're transmitting at!
