Good Morning,
Thank you for your query! You would be able to fit one coaxial cable inside this trunking, however, if this is to be installed round corners, the inflexibility of the cable would not allow for the trunking to close properly or be used with our accessory pieces. Due to this, I think the 30x15 profile would be a more suitable option for you.
Thank You
