I just bought a Phillips - Indoor HD antenna SDV2710/27 for $19.99. I plugged it into my converter box and instantly noticed marked improvement. I'm picking up 15 channels with clear strong signals and without having to move the antenna around. With my previous rabbit ears I got about 10 channels, but would have to go to great lengths in order to find the best positions for the antenna to pick them up. I am quite happy with this twenty-dollar purchase. I think it is well worth the money.
