Ancor marine grade coaxial cable.
High quality, tinned conductor and outer braid.
UV inhibited white jacket. Has never been used in the sun.
RG8X type - 50 ohm.
Better durability and lower signal loss than RG58.
I have a 112 inch long piece of it left over from a project in my boat. I know it's a long shot, but I'd like to give it to someone who will use it rather than throw it away.
I just priced it at $22.41 from West Marine. That's not a ton of money, but it might also save you a long drive if you're in the neighborhood. I also go down to Harbor Island once or twice a week, so could also hand it off there if that is more convenient. Message me to make arrangements.
