Pros: I was able to split my satellite signal to 2 TVs, which enabled one tv to be on satellite and the other on a regular outside antenna, without having to use an A-B switch. You can just change the input to the TV's. The owner of an electronics store store told me that RCA splitters were not made and if I did find one, the video signal probably would not work, but it did!
I would recommend these RCA splitters. They work great!
I've bought a few of these to split composite and component video signals, and they work pretty well. They come individually packaged. The signal seems to be transmitted just fine, but the cables I'm using are only about 10' at the longest. The only downside is that the connection is sometimes too tight or loose, so you might have trouble getting cables to stay put if you're moving them a lot, or you might have trouble getting the cables into the splitter.
