Which Cable contains more losses AC or DC?

1. If i take the cable to the maximum length , then which cable has more losses? 

2. I have 2 cables AC & DC Cable and from both the cables, I have to take one to the meter (upto 300 meters) so which cable should i carry so that the loss is low?

3. If  i am taking one of the two cables up to 300 meters, then some connectors or something have to be installed in the middle of the cable or can be taken directly to the meter?(If yes what is it?)

Try to upload a sketch of the circuit along with what the meter is supposed to measure for someone to make meaningful suggestions.
