I had an antenna that I was using for local channels. It was not doing a real good job for the digital channels. The installer did not install the Voom antenna. He said it really would not work in my area.
I tried the Radio Shack UHF antenna. This was okay, but one channel (the local Fox channel was only at 84 signal strength, and would break up on rainy and snowy days.)
I ended up ordering a Zenith Urban/Suburban Outdoor UHF HDTV/DTV Antenna, GEMDTV1 from the Walmart website. It arrived last night. It was a little more difficult to put together then the other antennas, but it was worth it. Channel 13 (The Fox Channel) is now at 92. After adjusting it a bit, all the channels come in between 92-98.
I live in Farmington, Utah and have a mountain with a high mineral content near me, and have to shoot across a Salt Water Lake to Farnley Peak where the digital signals are broadcast from.
This is the first antenna I have tried that I can actually get a good signal on all the channels.
