We just got ATT U-Verse at the house. Their wireless digital TV boxes are great. You connect the "transmitter to" your U-Verse modem, and you can move the reviever anywhere in the house. Range is very good. The Wireless U-verse boxes have pretty much any output you would ever want, HDMI, s-video, Composite, component, and RF on channel 3 or 4. The built in RF modulator is surprisingly good.
Here's my Philco Deluxe 23 fed from a U-Verse box.
