We tried these cables out during our investigation and they worked flawlessly. I scoured the internet for a great price and found it at http://www.radioshack.com/product/index.jsp?productId=3629874. It looks like this is a different brand that I bought but appears to be the same thing. It also comes with the connector. I know little about electronics and even I could figure out how to connect these cables. Love it! I give these BNC Extension Cables 5 spirits.
