You want Rg6 Quad shield, home depot carries it and you need to buy the matching end connectors. The regular sheilded connectors won't work. Also buy the correct tools to strip and crimp and lightly scrape the copper cable after you strip it, sometimes the plastic coating on the copper doesn't come off during the stripping process and will cause a bad signal if there is an improper ground. RG6 Quad Shield is better for long runs and reduces signal loss.
