I'm not too familiar with satellite boxes or whatever, but I have a Coolsat 5000 Platinum. I'd like to install it in another room, so I need to buy a cable extension and hook it with the existing cable. In other words, I need an extension for the cable that connects from the satellite to the Coolsat 5000 Platinum box. I've looked on Amazon and other sites. There are many different cables with different names. I'm not sure exactly which one I'm supposed to buy. Can someone show me an example? And what the exact name of this extension? Thank you!
