My husband will be replacing the old crank up antenna that is original to our 2016 GD Solitude 379 FL. We really wanted something smaller and more sleek so we've ordered the OA 1000 King Ominidirectional Antenna. He knows it takes 12 volts but he is trying to figure out where to hook it up or if it will be taken care of inside the cable. Is there a way to inject the 12 Volts DC someplace there than at the antenna coaxial cable? What did you all do?
