What are you using for an antenna? I guess DTV has been the reason for creating some new shapes of antennas, but the physics remain the same. So, there's not much reason to buy an antenna advertised for DTV if you can find an older one with the gain you need for the channels you watch. (keep in mind that the DTV signal is on a different channel (often UHF) than the analog, even if they claim the same channel number)

Oh, in an urban environment DTV is likely to be limited more by interference from reflected signals than signal strength, so a directional antenna, pointed in the correct direction should help.

How do you make a DTV antenna? Just remove the word "Color" from the box and replace it with "Digital".

I'm using plain ol' rabbit-ears-plus-UHF-loop connected via the BNC connectifier. I'm guessing that the rabbit ears are superfluous in this application, and if any 'DTV antennae' really do make a difference it'll be because they're an improvement over the loop (note the important 'if'). One antenna has a fancier-looking, plastic-coated UHF loop, a multi-position knob of uncertain function, and a wall-wart. I've got the bare-bones antenna connected to one DTV converter and the fancy one connected to the other, and whether its the antennae or the boxes that make the difference (I haven't gotten around to switching them around yet), one box gets crappy reception on a few channels and the other gets crappy reception on different channels.

I wasn't sure whether I could get away with ganging both converters onto one antenna, so I gave each converter its own. So far, anyhow.
