HDTV antenna update... I purchased a double bow tie antenna and a 20db amplifier from Radio Shack and my DTV/HDTV reception has improved quite a bit. I can receive all of the Atlanta DTV channels now (when they are broadcasting) except for Fox. If I switch back to the bigger Yagi antenna I can get Fox again. I guess I need to run another wire down from the attic and add an A/B switch.
