Personally its more the CCS center (and likely foil and aluminum shield) that would turn me away from what you have. I have always used a CCTV grade coax RG59 or RG6 that has a copper braid and solid copper center for baseband video applications. There are some companies that make premade coax/power cables that might work well for you. I have used these from vanco [Link: vanco1.com]
