Query: Pretty Disappointing

I have used a similar device from Radio Shack for years. But my old relay had its antenna busted which hurt the picture quality. I ordered this as a replacement.Sitting in the exact same spot this RF-Link was worse than my 4 year old broken antenna Radio Shack. The distance was 12 feet with a single sheet rock / 2x4 interior wall between them. All on the same floor.I'm just going to drill a hole in the wall and run coax.
